Find the value of x.<br> A) 21 <br> B) 27 <br> C) 31 <br> D) 34
Ivahew [28]

The 2 angles given are vertical angles, which mean they are the same.

So we have: 3x +1 = 64


Subtract 1 from each side:

3x = 63

Divide both sides by 3:

X = 63 / 3

X = 21


The answer is A.

Please help! I am stuck on this
DaniilM [7]

Answer:

c.

Step-by-step explanation:

Assuming we are not restricting the domain of f, the inverse isn't a function

\frac{1}{ {x}^{2} }  - 7

y =  \frac{1}{ {x}^{2} }  - 7

x =  \frac{1}{ {y}^{2} }  - 7

x + 7 =  \frac{1}{ {y}^{2} }

{y}^{2}  =  \frac{1}{x + 7}

y =  \sqrt{ \frac{1}{x + 7} }

Since square root are Positve or negative, the function will not be a function.

The correct answer is c.
