Answer: C

Step-by-step explanation: With inverse equations, you switch y and x (y=f(x)) and undo/reverse the steps towards x.

1. Multiply by 3

2. Add 2

Equation by itself

0. x

1. 3(x)

2. 3(x+2)

If y=15 when x=3/4, find x when y =25. Show work please!
-BARSIC- [3]

Set up a proportion: x/y = x/y

(.75)/(15) = (x)/(25)

Then cross multiply:

(.75)(25) = (15)(x)

18.75 = 15x

x = 1.25 or (5/4)

There you go :)

20 x 0.05 = 1

20 + 1 = 21
