Answer:
Step-by-step explanation:
We must find the inverse of the following function:
to solve this, you change f(x) by y
y=
exchange the variables:
You clear the variable "y"
9(x+2) = y
y = 9(x+2)
y = 9x +18
finally you change "y" to f ^-1 (x) =
f^-1 (x) = 9x+18
15 the answer is 15 60/4 is15 15*4=60 which is 4 times bigger

hope it helps and have a wonderful day
4(2 - x) > -2x - 3(4x + 1)
8 - 4x > -2x - 12x - 3
-4x + 2x + 12x > -3 - 8
10x > -11
x > -11/10
x > -1.1
12/(5x-2)=(12+4)/6x
72x=80x-32
8x=32
x=4
