A(-2,-5) is a glide reflection wear the translation is (x, y) is x+7,y and the line of reflection is y=2 what is a’

point A' is (5, 9)

Step-by-step explanation:

A (-2,-5) is a glide reflection wear the translation is (x,y) is x+7,y and the line of reflection is y=2

A is (-2,-5)

a glide reflection wear the translation is (x,y) is (x+7,y)

7 is added with x, so add 7 with x  value -2 on A(-2,-5)

(-2+7, -5)

(5,-5)

Reflection is y=2

So we need to find the difference of y values of point (5,-5) and y = 2

2-(-5) = 7

So we move 7 units up from y = 2. y=2+7 = 9

x value remains the same x=5

Hence point A' is (5, 9)

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
