The answer is -34.72. I have attached a picture of the work. I hope this helps. :)
Answer:
A.True
Step-by-step explanation:
To find the midpoint of a line segment, we find the averages/mean of the endpoints of the line segment.
Midpoint Formula:
M(x,y)=(x₁+x₂/2 , y₁+y₂/2)
a. 7x + 52 (2x + 5x) (40 + 12)
b. 13x + 142 (2x+5x+6x) (40 + 12 - 10)
c. 246 (16 + 40 + 40 + 100 + 12 + 48 - 10)
Answer:
C
Step-by-step explanation:
Perpendicular lines have the exact opposite slope of the other equation.
So the slope will be x or 1x. Plug in
-8 = 1(4) + b (b represents y-intercept) like y=mx+b
-8 = 4 + b (subtract 4 on both sides)
-12 = b
The equation is y = x - 12
C
solve
y + 8 = x - 4 (subtract 8 on both sides)
y = x - 12
