Geoffrey is evaluating the expression (-3)^6(2^6)/(-3)^5(2^2) as shown below.

Alekssandra [29.7K]

Answer:

48.

Step-by-step explanation:

First you multiply the number by itself as many times as the number of the exponent is. In this case you multiply -3 to itself 6 times which makes -729, 2 to the 6th power is 64, -3 to the 5th power is -243, and 2 to the 2nd power is 4. Then you multiply -729 by 64 which makes -46656 and multiply -243 by 4 which makes -972, and then divide -972 from -46656 which makes 48.

Find an equation for the perpendicular bisector of the line segment whose endpoints are (-9,-8) and (-5,6) (ill give u the brain

nikklg [1K]

Step-by-step explanation:

slope of the segment through (-9, -8) and (-5, 6) is (-9-(-5))/(-8-6)=-(-4)/(-14)=2/7

this means the slope of the perpendicular is -7/2.

the midpoint of the segment is (-7, -1)

so the line is y+1=(-7/2)(x+7).
