Answer:
False
Step-by-step explanation:
first step is
x+y = 30
x-y = 12
The inverse function for the given function f(x) = 4x - 2 is x/4 + 2
or, f⁻¹(x) = x/4 + 2
Given function, f(x) = 4x-8
We have to find f⁻¹(x)
f(x) = 4x - 8
or, y = 4x - 8
Interchanging the x variable with y,
x = 4y - 8
Solving y,
x = 4(y - 2)
or, x/4 = y - 2
or, y = x/4 + 2
Now, replacing y with f⁻¹(x), we get;
f⁻¹(x) = x/4 + 2
For verifying, you can use
(f · f⁻¹ )(x) = x
Therefore, the inverse function of f(x) is x/4 + 2.

Divide 4 by 5 which is 0.8 and you need to find c aka the number that makes 0.8 a whole number
Answer:
18
Step-by-step explanation:
Write double you used. is twice of what I used so
8+10=18
or
4+4+5+5=18
or 4+5=9*2=18
