Answer:
y=1/2x-3 1/2
Step-by-step explanation:
use change in y over change in x to solve for the slope... -1+2/5-3=1/2
then use point slope form with the slope to simplify for the slope intercept form... either point works, i used (3,-2)
y+2=1/2(x-3)
y+2=1/2x-3/2
y=1/2x-3/2-2
y=1/2x-3 1/2

$ per min is a rate. you multiple by minutes to get dollars.
A = 10x
B = 5x + 20
set them equal to find minutes, x.
10x = 5x + 20
10x - 5x = 20
5x = 20
x = 4
Answer:
Step-by-step explanation:
a - 2.5 = 4.5
2.5 = 2.5
a = 7.0 or 7
