HJ + JM =

0

Step-by-step explanation:

Coordinate of H = -3

Coordinate of N = 3

= |-3 - 3| = |-6| = 6

Midpoint of is ½ the distance of = 3.

Therefore, coordinate of the midpoint of is the coordinate of H + 3 = -3 + 3 = 0

Or

The coordinate of N - 3 = 3 - 3.

Therefore, the midpoint of is 0.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3
