If y=80 when x=32, find x when y=100.

Y        X

80     32

100    x'

Step-by-step explanation:

80x' = 100*32

80x' = 3200

x' = 3200/80

x' = 320/8

x' = 40

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

a reflection across the x axis and a 90 degree rotation left and right.
