Answer:

A,C,D

Step-by-step explanation:

a linear equation is in the form of y=mx+b

in this case slope m is unidentified and there is no y intercept, and x=3 vertical line.

A) the equation is x=3 ( right answer)

x=3 is not a function in the normal sense

however in this case we might say that the relation ship is 3

so the Domain and the range equal to 3

An angle bisector divides an angle into equal parts.

<em>The value of x is 7</em>

The given parameters are:

$\angle BAE = 9x + 2$

$\angle BAD = 130^o$

Line AE is the angle bisector of $\angle BAD$

This means that:

$\angle BAD = 2 \times \angle BAE$

So, we have:

$130 = 2 \times (9x + 2)$

Divide both sides by 2

$65 = 9x + 2$

Subtract 2 from both sides

$63 = 9x$

Divide both sides by 9

$7 = x$

Rewrite as:

$x = 7$

Hence, the value of x is 7
