Answer:
Step-by-step explanation:
if (x,y)is mid point of two points (x1,y1) ,(x2,y2) then
x=(x1+x2)/2
and y=(y1+y2)/2
coordinates of M are ((-2+(-8))/2,(-7+7)/2)
or are (-5,0)
Answer:
Step-by-step explanation:
Given the system of equations:
2x + 3y = 15
X + 3y = 0
What is x?
2x + 3y = 15
X + 3y = 0 subtract the bottom equation fron the top one
2x - x + 3y - 3y = 15 - 0 see how the 3y - 3y equates to zero
2x - x = 15
x = 15 Now for extra credit what is y?
X + 3y = 0
15 + 3y = 0
15 - 15 + 3y = 0 - 15
3y = -15
3y/3 = -15/3
y = -5
-15
