Answer:
B. 3/2
Step-by-step explanation:
If f(x) and are inverse, that means that if we switch the x and y for f(x) and solve for y, we will get the inverse function.
Knowing that f(x) = 2x + 5, let's write this as y = 2x + 5 and switch the x and y:
x = 2y + 5
Now, solve for y:
x = 2y + 5
x - 5 = 2y
y = (x - 5)/2
That's the function:
Plug in 8 for x:
The answer is thus B.

Answer:
=
Step-by-step explanation:
Given
= =
This can be expressed in 2 parts as
= ( cross- multiply )
3x = 10 ( divide both sides by 3 )
x =
and
= ( cross- multiply )
2y = 15 ( divide both sides by 2 )
y =
Thus
= = × ( cancel 10 and 15 by 5 )
= × =
