Which ordered pair is the reflection of (5,-8) across the x axis and the y axis?

(-5,8)

Step-by-step explanation:

Given : Point (5,-8)

To Find : Which ordered pair is the reflection of (5,-8) across the x axis and the y axis?

Solution :

The given point lies in 4th quadrant

The reflection of the point (x,y) across  the x-axis is the point (x,-y).

Thus the reflection of (5,-8) is (5,8)

The reflection of the point (x,y) across the y-axis is the point (-x,y).

Thus the reflection of (5,-8) is (-5,8)

Hence (-5,8) ordered pair  is the reflection of (5,-8) across the x axis and the y axis.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
