Answer:
c
Step-by-step explanation:
Okay, so first you make f(x) = y and switch x and y. So the equation becomes:
x = y^2 - 16
The next step is to get y by itself. So first you add 16 to both sides:
x + 16 = y^2
Now you square root everything, so the final answer is going to be:
the square root of x + 4 = y
This is a percent problem which means
You take the amount that has been completed over the total amount. You then multiply it by 100%
30/120*100=25%
Answer:
15% if I remember correctly
The answer is c. 9z^7/y^6
