Step-by-step explanation:

y+64=180

y=180-64=116°.

y=4x-28 (vertically opposite angle)

116=4x-28

116+28=4x

144=4x

x=36°.

hope this helps you.

Which equation represents a proportional relationship? Y=-5(x+1). Y=5x+1. Y=-x. Y=1/5x

Tema [17]

A proportional relationship is also a direct variation.
The general equation of direct cvariation is

y = kx,

where k is a number.

In your case, if k = -1, then y = kx becomes y = (-1)x which is the same as

y = -x

Answer:

4±√5

EXPLAINED ANSWER:

Since the variable is a binomial and it is squared, we apply square root on both side, and apply the ± sign on the right side (since the solution of a square root can be both positive and negative), and later pass the 4 positive to the other side.

√25 can be (5)(5) or (-5)(-5)
