Opposite angles of a quadrilateral inscribed in a circle are supplementary, so their sum must equal 180°.

A. 72° + 108° = 180° Answer: yes

B. 66° + 114° = 180° Answer: yes

C. 80° + 90° = 170° Answer: no

D. 64° + 106° = 170° Answer: no

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

svp [43]

To find the inverse we have to first change the function notation to 'y'

So

f(x) = -x becomes y = -x

Next, we have to switch the x and y values

So, y = -x becomes x = -y

Now, we have to solve for y.

y = -x

So the inverse of f(x) = -x is:

$f^{-1}(x) = -x$

Answer:

3.) (x + 5) (x - 6)

Step-by-step explanation:

Factor the following:

x^2 - x - 30

Hint: | Factor x^2 - x - 30 by finding two numbers whose product is -30 and whose sum is -1.

The factors of -30 that sum to -1 are 5 and -6. So, x^2 - x - 30 = (x + 5) (x - 6):

Answer: (x + 5) (x - 6)
