Find the coordinates of the midpoint of ab if a(-8, 7) and b(-9, 11).

M[-8½, 9]

Step-by-step explanation:

The quickest way to do this is to calculate how far apart each corresponding coordinate is, then take HALF of that range:

From -8 to -9 → -1

From 7 to 11 → 4

-8 - ½ = -8½ [x-coordinate]

→ [-8½, 9]

7 + 2 = 9 [y-coordinate]

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
