Answer:
12/7
Step-by-step explanation:
To set up a ratio of "thing 1" to "thing 2", build a fraction with "thing 1" on top (numerator) and "thing 2" on the bottom (denominator).
The ratio of in-state students to out-of-state students is and this can be simplified ("reduced") by dividing both numbers by 9 to get the fraction 12/7.
We need the rest of the question :)
First find x in terms of f(x)
1/2 x = f(x) + 4
x = 2(f(x) +4)
x = 2f(x) + 8
Now replace x by the inverse function f-1(x) and the f(x) by x
f-1(x) = 2x + 8
f-1 (4) = 2(4) + 8 = 16
