First you do distributive property.
2c + 8 = 0
Then subtract 8 with 0
2c = -8
Then divide -8/2
<h2>c = -4</h2><h2>Hope this helps :)</h2><h2 />
The angle immediately below x makes up the third angle of the isosceles triangle whose base angles are 55°. That third angle and x are "vertical" angles, hence equal. The value of x can be found from the sum of angles of a triangle:
x + 55° + 55° = 180°
x = 70°
The appropriate choice is the 2nd one:
70°
Answer:
Option B

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem the only linear function that passes through the origin is

where
The constant of proportionality is k=3/4
