The S in supplementary<span> can be used to form the 8 in 180. The C in </span>complementary <span>can be used to form the 9 in 90. If we know that a set of </span>angles<span> form one of these special relationships, we can determine the measure of the other </span>angle<span>. To determine the supplement, subtract the given </span>angle<span> from 180.</span>

What is the inverse of the function f(x) = x - 12?

ludmilkaskok [199]

Answer: $\displaystyle f(x)^{-1}=x+12$

Step-by-step explanation:

First, we will rewrite the function in terms of <em>y</em> as in y = x - 12.

Second, we will swap the x and y values.

y = x - 12

x = y - 12

Third, we will solve for y. In other words, we will isolate the <em>y</em> variable and get it "by itself" on one side of the equal sign.

x = y - 12

x + 12 = y

y = x + 12

Lastly, we will change y back into terms of the function, but the inverse.

$\displaystyle f(x)^{-1}=x+12$

Answer:

C) (8,12)

Step-by-step explanation:

$MP= (\frac{x_1+x_2}{2} )(\frac{y_1+y_2}{2} )\\MP= (\frac{5+11}{2} )(\frac{9+15}{2} )\\MP= (\frac{16}{2} )(\frac{24}{2} )\\MP= (8,12)$
