What is the question please help!
Answer:
92
Step-by-step explanation:
angle a and b add up to 180 degrees
4x-20+2x+8=180
add like terms
6x+12=180
x=28
then substitute to get 92
Simplify -5x + 12 - 7x to -12x + 12
-12x + 12 = -3(5x + 8)
Expand
-12x + 12 = -15x - 24
Add 15x to both sides
-12x + 12 + 15x = -24
Simplify 12x + 12 + 15x to 3x + 12
3x + 12 = -24
Subtract 12 from both sides
3x = -24 - 12
Simplify -24 - 12 to -36
3x = -36
Divide both sides by 3
x = -36/3
Simplify 36/3 to 12
<u>x = -12</u>
Should have the ordered pairs of
(-4,4) (-3,3) (-2,2) (-1,1) (0,0) (1,1) (2,2) (3,3).
Will look like a V when graphed. Reason being is if you take the absolute value of anything you are basically just dropping the negative sign as it is how far away it is from 0.
