To determine the expression that is equivalent to 8a + 20, all you have to do is find the common denominator and divide the values by it.

8a + 20
8a/4 + 20/4
4(2a + 5).

The correct solution would cue the second option - 4(2a + 5).

K= 100

You use distributive property

Step 1: −(−k)−1(−86)+10=−4

Step 2: k−1(−86)+10=−4

Step 3: k+86+10=−4

Step 4: k+96=−4

Step 5: k=−96−4

Step 6: Subtract 4 from −96 to get −100.

Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x.

Molodets [167]

$f(x)= \frac{x-9}{x+5}$
$g(x)= \frac{-5x-9}{x-1}$
$f(g(x))= \frac{ \frac{-5x-9}{x-1} -9}{ \frac{-5x-9}{x-1}+5 }$
$f(g(x))= \frac{-5x-9-9(x-1)}{-5x-9+5(x-1)}$
$f(g(x))= \frac{-5x-9-9x+9}{-5x-9+5x-5}$
$f(g(x))= \frac{-14x}{-14}=x$
$g(f(x))= \frac{-5 \frac{x-9}{x+5}-9 }{ \frac{x-9}{x+5}-1 }$
$g(f(x))= \frac{-5x+45-9(x+5)}{x-9-1(x+5)}$
$g(f(x))= \frac{-5x+45-9x-45}{x-9-x-5}$
$g(f(x))= \frac{-14x}{-14}=x$
