Answer:
haiii i can only solve for the vertex...
Step-by-step explanation:
so to find the vertex you have to make it to
y - h = a(x - k)^2
i think
(you could also just make it y = a(x - k)^2 + h but i like the second one better)
soo
y + 5 = 3(x + 7)^2
the vertex is
(-7, -5)
and ummm i think the axis for the axis of symmetry .ss
x = 2a/b but im not sure

1. What are the perimeter and area of a rectangle with a length of 20 in. and a width of 15 in.? (1 point)
P = 35 in., A = 300 in.2
P = 70 in., A = 300 in.2
P = 300 in., A = 70 in.2
P = 35 in., A = 200 in.2
Answer:
It's the 2nd one
Step-by-step explanation:
So to find the perimeter you add all the sides together. So if 2 of the sides are 20 and 15, that means the other ones are 20 and 15.
Once you add those all together you get 70.
To find the area you multiply the two different sides, so that would be 20 and 15.
20 times 15 is 300.

1. The media reported that Olympic gold medalist Michael Phelps regularly consumed at least 8,000 calories per day when he was training for the Olympics. In order to do this, he ate at least three extra-large meals and also consumed a maximum of 2,000 calories worth of special energy drinks each day.
a.Write and graph an inequality to represent the number of calories from energy drinks Michael Phelps drank per day while training
b.Write and graph an inequality to represent the total number of calories Michael Phelps consumed each day.
2. Write a situation about Michael Phelps in which the inequality 3m + 2,000 ≥ 8,000 would represent the situation.
3. To keep from losing weight while training, athletes must not burn more calories than they consume in a day. On one day, Michael Phelps burned 1,000 calories per hour while swimming and an additional 3,000 calories while out of the pool. Write and solve an inequality to estimate the number of hours he swam that day if his daily average caloric intake was at most 9,000 calories.
4. An athlete wants to maintain a net caloric intake of no more than 2,000 calories for the day.
a. Write and solve an inequality to determine how many hours she must train if she burns an average of 750 calories per hour and eats a total of 8,000 calories.
b. Graph the solution to your inequality on a number line. Explain why your answer to part a is a solution to this situation.
c. If she trains 8 hours per day, what is the greatest caloric intake she can have to keep from losing weight? Explain your reasoning.

Answer: This is the anwser to test 1
The X on the start is 46 then just do 46 + 18 = 64 This is the anwser for letter A
This is gonna be the awnser for letter B
There are 46 students in the filmaking club and 18 on the yearbook
Test 2
This is the awnser to letter A The cost of the adult ticket is 8 dollars
So it will be 8 + 4 = 1,040 if its wrong then you can put 520 or just divide it example: 8 divided by 520, 4 divided by 520
Awnser for letter B is
Each adult ticket cost = 8 dollars
Each student ticket cost = 4 dollars
Hope it helps :)

Determine the value of ? in the figure below.
Answer:
about 6.9
Step-by-step explanation:
first we have to find the missing side that doesn't have a "?". we can do this using pythagorean theorem. using the equation a^2 + 1^2 = 5^2 we know that this side is about 4.8. using this, we can use 4.8^2 + 5^2 = c^2. then, after doing this, we get about 6.9.
Consider the systems of linear equations in the table below.
Identify which system has no solution. Then, graph and label the equations for that system on the coordinate plane.
Step-by-step explanation:
no solution is when numbers on either side of the equal sign are different
have both equations in each system look like
y = ....
then since both are equal to y
have both equations equal to each other to get the value of
x
system 1:
6x+3=6x+3
0=0
infinite
system 2:
1/2x-5= -2x-4
5/2x=1
x=2/5
one solution
system3
4y-x= -4
y=(x-4)/4= 1/4x-1
1/4x-1= 1/4x-1

Solve the problem by making a table and then making a graph.
This year, Ms. Makratzaki’s small hardware store had sales of $536,000. Five years ago, the store had $441,000 in sales, and last year it had $517,000 in sales. Assuming a constant rate of increase, predict the amount of sales the store will have after 8 years.
a.
$650,000
b.
$669,000
c.
$688,000
d.
$707,000
Please select the best answer from the choices provided
A
B
C
D
Thinking it as a propotional increase, find the unit rate of change.
values: (0, 536,000), (-5, 441,000), (-1, 517,000)
unit rate of change:
[tex]\sf \dfrac{y2-y1}{x2-x1}[/tex]
[tex]\dashrightarrow \sf \dfrac{536,000-441,000}{0-(-5)}[/tex]
[tex]\dashrightarrow \sf 19000[/tex]
Therefore, the sales increase by $19000 each year.
After 8 years the sale increasement:
$19000 * 8$152000Total sales amount:
current sales + increasement in sales$536,000 + $152000$688,000So, correct answer is : $688,000

Which correctly describes a cross section of the right rectangular prism if the base is a rectangle measuring 15 inches by 8 inches? Select three options.
A cross section parallel to the base is a rectangle measuring 15 inches by 8 inches.
A cross section parallel to the base is a rectangle measuring 15 inches by 6 inches.
A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.
A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 4 inches by 15 inches.
A cross section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches.

Find the mean of the data in the bar chart below.
Answer:
9/2≈4.5
Step-by-step explanation:
mean is 4, 5,6,3
Find the mean of the list:
(4, 5, 6, 3)
The mean of a list of numbers is given by:
(sum of elements)/(number of elements)
(sum of elements) = 4 + 5 + 6 + 3:
(4 + 5 + 6 + 3)/(number of elements)
Counting, we see that the list has 4 elements:
(4 + 5 + 6 + 3)/4
4 + 5 + 6 + 3 = 18:
18/4
18/4 = 9/2:
Answer: 9/2≈4.5

Answer:
111-(9*12)=3.
Step-by-step explanation:
There are 111 ounces of orange paint, which is going to go into the other bottles. How many bottles? 9. However, because in life we have different sized bottles, it states each bottle takes 12 ounces. In order to find the amount of ounces needed to find all 9 bottles, we first multiply 9*12, which equals 108. Filling all the bottles with orange paint will take up 108 ounces of the orange paint. We do have enough, since we have 111 ounces, but we must find how many ounces we have now that we've used up 108, which can be done by subtraction. 111-108=3. We have 3 ounces left over.
Now we translate everything we did into a mathematical equation. First, we multiplied, and then we subtracted the product from 111. 111-(9*12), which equaled 3, so 111-(9*12)=3. The parentheses technically aren't necessary, because if this is solved according to PEMDAS (the order of operations), the multiplication will occur first anyway.

Cole has a rectangular garden
square meters. The length of
the garden?
4.5 meters. What is the width, in meters, of
garden is
Answer
The width is 3.56
Step-by-step explanation:
Area=length × width
The area is 16.02
The length is 4.5
The width is unknown so we are going to call it X
4.5X=16.02
divide 16.02/4.5 = 3.56
