A coal mine worker is 650 ft below the ground in a mine. Another coal mine worker is 7 ft above ground operating mercenary. A: Write a integer for the position of each worker relative to the ground.
B: Fine the absolute value of each integer.
C: Witch worker is farther from the ground surface.

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

-14 is the answer

hope this : ))

21

step-by-step explanation:

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
