Answer:
8. 500.8
9. 5008
10. 50080
Step-by-step explanation:
The greatest common divisor of these numbers is 12.
After 19 months, the cost will be same for both memberships.
Step-by-step explanation:
Given,
Sign up fee at Power Plus = $22.00
Per month fee = $34.14
Let,
x be the number of months.
P(x) = 34.14x + 22
Sign up fee at Heavy Hulk = $34.50
As they have cut the cost into half.
Sign up fee = 
Per month fee = $34.39
H(x) = 34.39 + 17.25
For same cost ;
P(x) = H(x)

Dividing both sides by 0.25

After 19 months, the cost will be same for both memberships.

To graph the equation of the line, find the x-intercept and the y-intercept of the function
we have

we know that
The x-intercept is the value of x when the value of y is equal to zero
The y-intercept is the value of y when the value of x is equal to zero
Step 1
<u>Find the x-intercept</u>
For 



the x-intercept is the point 
Step 2
<u>Find the y-intercept</u>
For


the y-intercept is the point 
Step 3
Graph the points and draw the line
