A = 50/2
= 25
B = 20/4
= 5

Answer:
y=-3x-7
Step-by-step explanation:
Here's why we know that if a line is parallel to another they never cross so they must have the same slope. Then we plug in the values y=mx+b, y=-3x+b, then plug in x and y, -4=3+b, b=-7, therefore the equation is y=-3x-7
Answer:
20
Step-by-step explanation:
The angles are vertical angles which means they are equal
60 = 2x+20
Subtract 20 from each side
60-20 = 2x+20-20
40 =2x
Divide by 2
40/2 = 2x/2
20 =x
