Answer with Step-by-step explanation:

Amaya used these steps to solve the equation 8x + 4 = 9 + 4 (2x-1).

Which choice describes the meaning of her result, 4=5?

on solving the equation

8x+4=9+4(2x-1)

distributing 4 with both 2x and -1

8x+4=9+8x-4

8x+4=5+8x

subtracting both sides by 8x yields

4=5

She distributed the 4 to the 2x-1, giving her 9+ 8x -4. she subtracted 8x from both sides leaving her with 4=9-4 which is the same as 4=5

Answer:

A(3,3) S(4,0) T(5,4) J(4,5)

Step-by-step explanation:

Hope this one helped too! You just need to find the x=1 line (goes in this direction --, is where x is constantly 1) and count how far each point is from it and go over the line that amount if that makes sense. The x's stay the same in this one and the y's change.
