Step-by-step explanation:
-(4b-6b-7b)
= -4b+6b+7b
=9b
m = (y2-y1)/(x2-x1)
m = (6-4)/(4-0)
m = 2/4
y = mx + c
6 = (2/4)(4) + c
c = 4
Thus, the equation is y = (2/4)x +4
Answer:
Commutative property
2/4 is equal to 1/2
1/2 is equal to 2/4 because 1/2 x 2 for each the numerator and the denominator.
C
use y=mx+c
follow the flow
50+90+3x+1=180.....................
