If R is the midpoint of PS with PR = 7x + 23 and RS= 13x-19 then find PS

Rainbow [258]

If R is the midpoint of PS, then PR = RS -- (1)

Also, PR + RS = PS -- (2)

__________________

PR + RS = PS

7x + 23 + 13x - 19 = PS

__________________

Now, PR = PS

7x + 23 = 13x - 19

7x - 13x = -19 - 23

-6x = -42

x = -42/-6

x = 7

__________________

PS = 7x + 23 + 13x - 19

PS = 7(7) + 23 + 13(7) - 19

PS = 49 + 23 + 91 - 19

PS = 144 

Hope it helps!

Answer:

The last/bottom graph

Step-by-step explanation:

I would assume it the bottom on because when you reflect off the y-axis, you don't reflect of the y-axis line. You reflect of the x-axis, it is weird.
