Answer: (A) and (B) are the same

Step-by-step explanation:

for (A)

x-=x+4

x=x-(x+4)

x=x-x-4

x=4

for (B)

x=x+4-x

x=4

for (C)

x=x-(x+4)

x=x-x-4

x=-4

so (A) and (B) are the same because the value of their x is +4

Answer:

(-9, -5)

Step-by-step explanation:

Ok, so when you move an image to the right, you are moving along the x-axis, and when you move up, you are moving up the y-axis. So if the altered image is (x,y) and the values are (-5, -1), you reverse what has been done to the image. In this case, since we moved to the right 4 units, we know that means we added 4 to x, so we subtract 4 to get -9. And then, for the y-value, because we added 4, we do the opposite, and subtract 4 to get -5. So the pre-image should be (-9, -5)
