X + 3y – 2z = 3
-x – 2y + z = -2
2x – 7y + z = 1

x + 3y – 2z = 8

-x – 2y + z = 12

2x – 7y + z =7

this answer is fake

Step-by-step explanation:

x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1x + 3y – 2z = 3

-x – 2y + z = -2

2x – 7y + z = 1

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

1760 kilometers

multiply the amount of time the plane took to travel by it's speed
