Remember that in PEMDAS, you do the parentheses first.

1. For each answer choice, do whatever is in the parentheses first.

2. Multiply that number to the one outside the parentheses

Hint: For this problem, If all the signs in the answer choice are multiplication, they will equal the same number.

If f(x) = 5x, what is f -1 (x) ?

Gala2k [10]

Answer:

$f^{-1}(x) = \frac{x}{5}$

Step-by-step explanation:

$f^{-1}\left( x\right) =y\Longleftrightarrow f\left( y\right) =x$

…………………………

f(y) = x

⇔ 5y = x

$\Longleftrightarrow y =\frac{x}{5}$

$\Longleftrightarrow f^{-1}(x) = \frac{x}{5}$

These three angles are on a line so must total 180°.
So 180-(52+58)=
180-110=70

So angle q is 70°.
