A person is riding a bicycle along a straight highway.
The graph at the right shows the rider's distance y in miles from a First Aid Station after x
hours.
(a) Find the slope-intercept form of the equation of the line.
Answer:
y=28/3x+6
Step-by-step explanation:
If you use the slope formula, y2-y1
_____\
x2-x1
You would get that the slope is 23/3 and you can see the y-intercept is 6 so you would get y=28/3x+6.
What is the percent of change from 5,000 to 8,000?
Step-by-step explanation:
% change = (new - original)/original × 100
= (8,000 - 5,000)/5,000 × 100
= 3,000/5000 × 100
= 60%

6.8127 *10^16
Step-by-step explanation:
Scientific notation is a way to make these numbers easier to work with. In scientific notation, you move the decimal place until you have a number between 1 and 10. Then you add a power of ten that tells how many places you moved the decimal.

The local craft fair charges the vendors a flat fee of $15 plus $5 for each hour that they spend at the fair. If the vendor owed how many hours did he remain at the craft fair ?
Answer:
Equation should be: 15x + 5 = y
Step-by-step explanation:
I do not know the amount of money that he owed
For Example :
15(12) + 5 = y
180 + 5 = y
y = 185

A. Rewrite the equation of the line in slope intercept form
B. Identify the slope and y intercept
(Show steps )
Answer:
Rewriting the equation in slope intercept form is: Y= -8x+4
Step-by-step explanation:
Im sure there's a faster way to solving this, but I'm just in 8th grade so I'm gonna apply what I know so far.
First of all, we know that our slope is -8... so we have y= -8x so far
From here, to find out y intercept I knew that our slope deals with all the points assigned, therefore we know that from -4 the change would be -8 so we get -12. We can also go the other way. This means that we plus 8 to get positive 4. (Side note: the change in our x value is 1 so we know that our y intercept is always dealing with a 0 in the x position) ex. (0,9) the y intercept would be 9.
To wrap things up, the slope is -8 and the y intercept is 4.
We then get Y= -8x+4
Hope this helps! :)
-3x + 9 = -3(2x + 3)+3(x-4)+1 how many solutions dos his equation have
Answer:
The answer is no solution or 0 solutions
Step-by-step explanation:
-3x + 9 = -3(2x + 3)+3(x-4)+1
−3x+9=−6x−9+3x−12+1
−3x+9=−3x−20
9=−20

Answer:
maria : 1/3 =0.3 line on top of three
franco:1/4=0.25
Step-by-step explanation:
tried my best hope its right :)
Answer:
Maria: 1/3 cups for each gallon
Step-by-step explanation:
Maria: 2/3 for every 2 gallons. 2/3:2
Franco: 1 1/4 for every 5 gallons. 1 1/4/:5
Okay, so I'm actually going to do it my way.
Maria : [tex]\frac{2}{3} = 4/6\\\frac{4}{6} /2 =2/6[/tex]
So, I simply turn it into a bigger fraction and cut it in half!
So, Maria uses 1/3 of a cup for each gallon
Hope this will help you figure out Franco's!!!

Answer:
f(4) = -28
Step-by-step explanation:
f(x) = -[tex]x^{2}[/tex] - 6x + 12
f(4) = -[tex]4^{2}[/tex] - 6(4) + 12
f(4) = -16 - 24 + 12
f(4) = -40 + 12
f(4) = -28

The intersection of a circle and a regular hexagon can be....
-two line segments
-a triangle
-two points
-a trapezoid
Answer: two points
Step-by-step explanation:
The intersection of a circle and a regular hexagon can be two pints option (C) two points is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
The intersection of a circle and a regular hexagon.
As we know, the polygon is a geometric figure with a finite number of sides in two dimensions.
On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.
If the circle and regular hexagon will intersect on a coordinate plane then it will create two intersection points.
Thus, the intersection of a circle and a regular hexagon can be two pints option (C) two points is correct.

Max has a Starbucks' gift card for $50. HIs favorite drink is the S'mores Frappuccino. Each drink costs $4.25. How many frappuccinos can Max purchase with his gift card? Write an inequality to represent the number of frappuccinos Max can purchase. How many frappuccinos can Max purchase with his gift card?
Answer:
4.25x ≤ 50
Number of drink = 11
Step-by-step explanation:
Given:
Amount of gift card = $50
Each drink cost = $4.25
Find:
Number of drink
Computation:
Assume;
Number of drink = x
So,
4.25x ≤ 50
x ≤ 11.76
so,
Number of drink = 11

find the line of the equation that passes through (3, -4) and is parallel to 3x + y + 2 = 0
leave your answer in the form of y = mx + c
hi
3x+y +2 = 0 so y = -3x-2
parrallel line has the same slope , so is -3x
then : -3 (3) +c = -4
-9 +c = -4
c = -4 +9
c = 5
so parallel is : y= -3x +5
