Answer:
D
Step-by-step explanation:
7 x 6 = 42 divided by 2 21 + 7 x 5 = 35 divided by 2 = 17.5 + 10 x 7 = 70 = 108.5
We are given the following function:
f(x) = 4/(x+2) - 2
We are asked to determine the inverse of this function. To do that we will first change the "f(x)" for "y":

Now we will switch "x" and "y", like this:

Now we will solve for "y", first by adding 2 to both sides:

Now we multiply both sides by "y+2":

Now we divide both sides by "x+2":

Now we subtract 2 to both sides:

Now we change "y" for the inverse of f(x), that is:

And thus we found the inverse. A similar procedure can be used for function 2.
When the value of x is 3, evaluate;

Substitute for the value of x into the parenthesis;

ANSWER:
The expression equals 40 (when x = 3)
Answer:
15
Step-by-step explanation:
H - 7
When H = 22, replace H with 22 in the equation.
22 - 7 = 15
