Answer:
1
Step-by-step explanation:
There us an understood one infront of the m.
Answer:
look i think is -5.005 I don't really know but I hope you get it right. Have a good day
Midpoint: ((x1+x2)/2, (y1+y2)/2)
-10+6 = -4/2 = -2
-4 - 5 = -9/2 = -4.5
Solution: (-2, -4,5)
-3x + y - 2z = 10 |* -1
3x - y +2z = -10
5x -2y -2z = 12
--------------------------- I add these equations term by term
8x - 3y = 2
-3x + y - 2z =10 ⇒ -3x + y - 2z =10
x -y +z = 23 | *2 2x - 2y + 2z = 46
----------------------------- I add these eq.
-x -y = 56
8x - 3y = 2
-x -y = 56
this is the system after i reduce it ( it has only two variables x and y)
