Answer:
r = 90
Step-by-step explanation:
Our goal is always to get the variable we're trying to solve for on one side of the =, and everything else on the other side. Since we are solving for r here, we want to get rid of the 20 first, and then the 2.
subtract 20 from both sides:
divide both sides by 2:
Answer:
D. y = -2x + 16
Step-by-step explanation:
The slope of a parallel line is the opposite reciprocal of the given slope so it'd be -2.
I think the formula is called point slope form? y-y1=m(x-x1).
y - 4 = -2 ( x- 6 )
y = -2x + 12 + 4
y = -2x + 16
Answer:
x = 3 thats all i know
