Answer:

x = 20

y = 40

Step-by-step explanation:

2x + 50

2(20) + 50 = 90

x + 30

20 + 30 = 50

5x/2

5(20)/ 2

100/2 = 50

180 - (90 + 50)

180 - 140 = 40

y = 40

F(x) = (1/2)x + 4
Plug y in for f(x).
y = (1/2)x + 4
Swap x and y.
x = (1/2)y + 4
Solve the equation for y =.
Subtract 4 from both sides.
x - 4 = (1/2)y
Multiply each term 2.
2x - 8 = y
Plug f^-1(x) in for y.
f^-1(x) = 2x - 8

f^-1(4) = 2(4) - 8
f^-1(4) = 0
