Answer:
64
Step-by-step explanation:
60 + 56 + x = 180
116 + x = 180
x = 180 - 116
x = 64
I believe the answer is 2x+2y= 20-21 or 2x+2y= -1. Think about Standard Form= Ax+By= C
Answer: y+1=-7 (x-5)
Step-by-step explanation:
The formula for point-slope form is y-y1= m (x-x1)
Step 1- Finding the slope by using formula
:
(5,-1) (6,-8) or (x1, y1) (x2, y2)
-8+1 = -7
6-5 = 1
Slope + -7/1 or -7
Step 2- Then insert numbers in point slope form:
y-y1 = m(x-x1)
y+1 = -7 (x-5)
