A.(- 2, 0) * and(3, 0).
2. The y-values are increasing on the interval from x = -3 to x = -1, and from x = 1 to x = 3. So the answer is B, -3 < x < -1.
What is x-intercept?
1. To find the x-intercepts of the quadratic function, we need to find the values of x for which y is equal to 0.
The x-intercept of a function is the point at which the graph of the function intersects the x-axis. At the x-intercept, the value of y (the output of the function) is equal to zero, which means that the corresponding input value of x causes the function to have an output of zero.
From the table, we can see that the function has x-intercepts at x = -2 and x = 3, so the answer is A.
What is an interval?
2. To determine where the function is increasing, we need to look for intervals where the y-values are increasing as x increases.
From the table, we can see that the y-values are increasing on the interval from x = -3 to x = -1, and from x = 1 to x = 3. So the answer is B, -3 < x < -1.

Find the equation of a line perpendicular to y = -6 that contains the point (1, 3). Write the equation in slope-intercept form.
Answers
The equation of a line perpendicular to y = -6 that contains the point (1, 3) is x = 1 .
Evaluating equation in slope-intercept form :We are given a line that runs through the point (1, 3) and is perpendicular to y = -6.
We want to write the equation for this line in slope-intercept form.
Slope-intercept form is y=mx+b,
where m is the slope and b is the value of y at the y intercept, hence the name. First, we need to find the slope (m) of the line.
Given line = y = -6
y = 0x - 6
compare with y = mx + C
therefore slope m = 0
the slope of the perpendicular line can be given as
M perpendicular = -1/m
M perpendicular = - 1/0
Keep in mind that we were given the line's perpendic subsequently, to find the slant of this line, we can do the accompanying condition
0m=1
Partition the two sides by 0
m = 1/0
This is indistinct - subsequently, the line has a vague slant . If so, then, at that point, it implies the line is an upward line
An upward line is composed as
x=k,
where k is the worth of x at the x side . The slope-intercept form cannot be used to write it.
Substituting 1 for k
y- y₁ = m perpendicular - ( x- x₁)
y - 3 = - 1/0( x - x₁ )
0 = - ( x- 1 )
x-1 = 0
x = 1
because this value is the same as the value of x at every point along such a line; in this instance, as indicated by the point (1, 3), this value is 1.
Hence, the equation of a line perpendicular to y = -6 that contains point 1,3 is x = 1 .

The drink of the people at large in Japan is green tea. The preparation of good tea is regarded by the Japanese as the height of
social art. For that reason, it is an important element in the domestic, political, and general life of the country.
Tea is the beverage--the masterpiece-of every meal, even if it be nothing but boiled rice. Every artisan and laborer, going to work,
carries a rice-box of lacquered wood, a kettle, a tea-caddy, a tea-pot, a cup, and chop-sticks. Milk and sugar are generally avoided. The
Japanese and the Chinese never indulge in either of these ingredients in tea. The use of these, they claim, spoils the delicate aroma.
From the highest court circles down to the lowliest and poorest of the Emperor's subjects, it is the custom in both Japan and China to
offer tea to every visitor upon his or her arrival. Not to do this would be an unpardonable breach of national manners. Even in the shops,
the customer is offered a soothing cup before the goods are displayed.
The Japanese believe that visitors to their homes are entitled to the best entertainment possible. As soon as a guest is seated upon a
mat, a small tray is set before the master of the house. Upon this tray is a tiny tea-pot with a handle at right angles to the spout. Other
parts of this outfit include a highly artistic tea-kettle filled with hot water, and a number of small cups, set in metal or bamboo trays. These
trays are used for handing the cups around, but the guest is not expected to take one. The cups being without handles, are not easy to
hold. The visitor must therefore be careful lest he or she let one slip through untutored fingers.
The tea-pot is drenched with hot water before the tea is put in. Then, more hot water is poured over the leaves, and soon poured off
into the cups. This is repeated several times. The hot water is never allowed to stand on the grounds over a minute.
The Japanese all adhere to the general household custom of the country in keeping the necessary tea apparatus in readiness. In the

The probability that a student chosen at random did not get a B 0.283 The probability of a student not getting a B is the number of students who did not get a B divided by the total number of students.
What does outcome mean?Outcome can be an event, such as the sum of two dice, or it can be a variable, such as the number of heads from a coin toss.
In this case, there are 21 students who did not get a B (2 male A's, 19 female A's, and 10 female C's), compared to a total of 74 students. Therefore, the probability that a student chosen at random did not get a B
= 21/74
= 0.283
To calculate this probability, we used the total number of students who did not get a B (21) divided by the total number of students (74).
This gives us the probability that a student chosen at random did not get a B.
In addition to using this method to find the probability of a student not getting a B, we can also find the probability of a student getting a B by subtracting the probability of not getting a B from 1.
In this case, the probability of getting a B would be
1 - (21/74)
= 0.71622.
This method can be used to calculate the probability of any outcome given the probabilities of all other outcomes.

The height in inches of a candle that has been burning for x hours is represented by the equation h=12−x . What is the meaning of the y-intercept in the context of the burning candle?
Answers
the y-intercept of the equation h=12−x represents the initial height of the candle when it is first lit, which is 12 inches in this case.
How to solve the question ?
In the given equation, h represents the height of the candle in inches and x represents the number of hours for which the candle has been burning.
The y-intercept of the equation is the point where the graph of the equation intersects the y-axis, which occurs when x is equal to 0. Substituting x=0 in the equation, we get:
h=12-0
h=12
Therefore, the y-intercept of the equation is 12, which means that when the candle is first lit (x=0), its height is 12 inches.
In the context of the burning candle, the y-intercept represents the initial height of the candle before it starts to burn. This is the height of the candle when it is first lit and before any wax has melted. As the candle burns and wax melts, the height of the candle decreases, and this is represented by the negative slope of the equation.
In summary, the y-intercept of the equation h=12−x represents the initial height of the candle when it is first lit, which is 12 inches in this case.

Performance Assessment
You are the student council member responsible for planning a school dinner dance. You will
need to choose a caterer, hire a band, analyze costs, and choose flowers for decoration. You
need to keep the ticket price as low as possible and still cover the costs.
Part 1 Choosing a Band
Band A charges a flat fee of $500 to play for the evening.
Band B charges $350 plus $1.50 per student.
Part A: Write a system of equations to represent the cost of the two bands.
Part B: Graph the system of equations and find the number of students for which the cost of
the bands would be equal.
Part 2: Choosing a Caterer
A caterer charges a fixed amount for preparing a dinner plus a rate per student served. The
total cost is modeled by the equation:
Total cost = fixed amount + rate * number of students
You know that the total cost for 50 students will be $450 and the total cost for 150 students
will be $1050. Find the caterer's fixed cost and the rate per student served. Explain your
answer.
Part 3: Analyzing cost
Use the information from Items 1 and 2. Assume that 100 students come to the dinner dance.
Decide which band you should choose and what the total cost per ticket should be to cover
the expenses of the band and caterer. Then repeat your calculations for 200 students.
Explain your reasoning.
Part 4: Choosing Flowers
You can spend no more than $500 on flowers for the event. A bouquet of daisies cost $25
each and a bouquet of roses cost $35 each.
Part A: Write and graph an inequality that represents the number of each type of flower that you can buy.
Part B: Suppose you buy 15 bouquets of daisies. What is the maximum number of bouquets

Answers
1.Band A: Cost = $500
Band B: Cost $350 + $1.50x
2. The caterer's fixed cost is $150 and the rate per student served is $6.
3.Cost per ticket $12.50
4.we can buy at most 3 bouquets of roses.
What are linear equations?
The first-degree equations are linear equations. The straight line's equation can be found here. ax+by+c=0 is the most common form of a linear equation, where a and b are zeros.
Part 1:
Let x be the number of students.
Band A: Cost = $500
Band B: Cost $350 +$1.50x
The system of equations representing the cost of the two bands is:
CostA = 500
CostB = 350+ 1.5x
Part 2:
Let F be the fixed cost and R be the rate per student served.
From the given information, we can write two equations:
50R + F = 450
150R + F = 1050
Subtracting the first equation from the second, we
get:
100R = 600
Therefore, R = 6.
Substituting R in the first equation, we get:
50(6)+F450
Therefore, F = 150.
So, the caterer's fixed cost is $150 and the rate per student served is $6.
Part 3:
For 100 students:
CostA 500
CostB = 350+ 1.5(100) 500
Both bands have the same cost, but Band A has a lower variable cost.
So, we should choose Band A.
Total cost for 100 students = 500 + 150+ 6(100) =
$1250
Cost per ticket = Total cost / Number of students = 1250/100 = $12.50
For 200 students:
CostA = 500
CostB = 350+ 1.5(200) = 650
Band A still has a lower cost, so we should choose Band A.
Total cost for 200 students 500+ 150 + 6(200) = $1850
Cost per ticket = Total cost / Number of students =
1850/200 $9.25
Part 4:
Let D be the number of bouquets of daisies and R be the number of bouquets of roses.
The cost of daisies is $25 per bouquet and the cost of roses is $35 per bouquet. We want to spend no more than $500, so we can write:
25D +35R < 500
If we buy 15 bouquets of daisies, then we can spend at most $425 on roses:
25(15) + 35Rs 500
375 +35R ≤ 500
35R ≤ 125
If we buy 15 bouquets of daisies, then we can.
Mathematics College spend at most $425 on roses:
25(15)+35R ≤ 500
375 +35R≤ 500
35R ≤ 125
R≤ 3.57
So, we can buy at most 3 bouquets of roses.

The value of tan2[tex]\alpha[/tex] = 6/7 where tan[tex]\beta[/tex] = 5/12 and sin[tex]\alpha[/tex] = 3/5.
What are the trigonometric identities are used to solve?Trigonometric identities allow us to formulate tan 2[tex]\alpha[/tex] in terms of tan[tex]\beta[/tex] and sin[tex]\alpha[/tex] as follows:
[tex]tan 2\alpha = \frac{ 2 tan \alpha }{1 - tan² \alpha }[/tex]
We know sin[tex]\alpha[/tex], so we can use the Pythagorean identity to find cos[tex]\alpha[/tex]
cos² [tex]\alpha[/tex] + sin² [tex]\alpha[/tex] = 1
cos² [tex]\alpha[/tex] = 1 - sin² [tex]\alpha[/tex] = 1 - ([tex]\frac{3}{5}[/tex])² = [tex]\frac{16}{25}[/tex]
cos α = ±[tex]\sqrt{\frac{16}{25} }[/tex]= ±[tex]\frac{4}{5}[/tex]
sin[tex]\alpha[/tex] and tan[tex]\beta[/tex] are both in the first or third quadrants because they are both positive numbers. Since cos[tex]\alpha[/tex] is positive, we can use the following positive root:
cos α = [tex]\frac{4}{5}[/tex]
Now we can use the tangent identity to find tan α:
tan [tex]\alpha[/tex] = [tex]\frac{sin\alpha }{cos\alpha }[/tex]=[tex]\frac{\frac{3}{5} }{\frac{4}{5} }[/tex]= [tex]\frac{3}{4}[/tex]
Next, we can use the Pythagorean identity to find tan² [tex]\alpha[/tex]:
tan² [tex]\alpha[/tex] + 1 = sec² [tex]\alpha[/tex]
tan² [tex]\alpha[/tex] = sec² [tex]\alpha[/tex] - 1
sec [tex]\alpha[/tex] = 1/cos [tex]\alpha[/tex] = 5/4
tan² [tex]\alpha[/tex] = (5/4)² - 1 = 9/16
Now we can use the formula for tan 2[tex]\alpha[/tex]:
tan 2[tex]\alpha[/tex] = 2 tan α / (1 - tan² α)
tan 2[tex]\alpha[/tex] = 2(3/4) / (1 - 9/16)
tan 2[tex]\alpha[/tex]= 6/7

So, the amount of sandwiches each student will eat is:
[tex]9[/tex] sandwiches / [tex]5[/tex] students

At this year's State Falr, there was a dice rolling game. If you rolled two dice and got a sum of 2 or 12, you won $12. If you rolled a 7, you won SS. Any other
roll was a loss. It cost $1 to play one game with one roll of the dice. What is the expectation of the game? Round your answer to the nearest cent.
The expectation of this game is approximately dollars.
Answers
Expectation of the gain for the given outcomes on rolling fair dice is:
E = $0.5
Explain about the total outcome:The total number of outcomes for such probability experiment is known as the total number of outcomes in probability.
For rolling sum 2 and 12 - {(1,1), (6,6)}
Total number of possible outcomes = 2 (that is 2 and 12)
As, either 2 or 12 will appear. So, there will be 1 gain and one loss.
Gain for rolling 2 or 12 is $12 and for loss $1
Gain = 12 - 1 = $11
For rolling sum 7 - {(1,6),(6,1),(2,5),(5,2),(4,3),(3,4)}
Gain for rolling 7 - $5 and for loss $1
Total number of possible outcomes = 6
Gain = 5 - 1 = $4
For others:
Total number of possible outcomes = 36 - (2+6) = 28
Loss = -$1
Expectation of total gain;
E = (2×11 + 6×4 - 28×1)/36 = 18/36
E = 1/2
E = $0.5
Thus, Expectation of the gain for the given outcomes on rolling fair dice is: E = $0.5

Answers
Answer:
To determine which investment option would yield the highest return, we can calculate the future value of each investment at a certain age. Let's assume we're looking at the value of each investment at age 65. Option 1: $50 initial investment with an average annual growth rate of 9% starting at age 30 Using a compound interest calculator, we can find that the future value of this investment at age 65 would be approximately $1,338. Option 2: $50 initial investment with an average annual growth rate of 8% starting at age 20 Again, using a compound interest calculator, we can find that the future value of this investment at age 65 would be approximately $1,088. Option 3: $100 initial investment with an average annual growth rate of 7% starting at age 25 Using the same calculator, we can find

enter an equation for which the solution is the daily room charge, in dollars per day, when a person stays at the hotel for 3 day and is charged a total of $234.
Answers
Using equations, the daily room charge, in dollars per day, is $78 per day.
What are Equations?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let x be the daily room charge, in dollars per day.
Then the total charge for staying for 3 days is 3x dollars.
According to the problem statement, the total charge for staying for 3 days is $234. So we can set up the equation:
3x = 234
To solve for x, we can divide both sides by 3:
[tex]3x/3 = 234/3[/tex]
x = 78
Therefore, the daily room charge, in dollars per day, is $78 per day.

2x + 5y = 4
2x - y = -8
Answers
We get x = -3 and y = 2 on solving 2x + 5y = 4; 2x - y = -8
Let's find y from the second equation in terms of x:
2x - y = -8
-y = -2x - 8
y = 2x + 8
Now, we may enter the following expression in place of y in the first equation:
2x + 5y = 4
2x + 5(2x + 8) = 4
Simplifying this equation, we get:
12x + 40 = 4
Subtracting 40 from both sides, we get:
12x = -36
Dividing both sides by 12, we get:
x = -3
Now we can substitute this value of x into our expression for y:
y = 2x + 8 = 2(-3) + 8 = 2
Hence, x= -3 and y= 2 are the answers to the system of equations.
The complete question can be:
2x + 5y = 4
2x - y = -8
solve for x and y
