Answer:
y is directly proportional to 8
while x is inversily proportional to 8
Given the function, f(x) = 9 - x :
To evaluate f(4), we must substitute 4 into the given function as an input value for x:
f(4) = 9 - 4
f(4) = 5
Therefore, f(4) = 5.
replace x = 7 into the equation
f(7) = 7/9 - squared root (7-3)
f(7) = 7/9 - squared root (4)
f(7) = 7/9 - 2
f(7) = -11/9
f(7) = -1.22

Step-by-step explanation:
I'm not doing all of them, so you can learn.
Here's the first three:
9. 6-12x
10. (and 11? dude u need to rephrase) x/(5(x+2))
