Answer 3

after it's reflected across the x-axis means instead of y, sub -y
the points you get are the coordinates of the new rectangle , the intersection point is the midpoint along both diagonals, so you can plot the rectangle to see which points does any diagonal pass and find the length of the diagonal then the midpoint

Answer 4

I hope that was helpful

Answer 5

(4, 4.5)

(-4, 4.5)

(4, 2.5)

(-1, -4.5)]

I apologize. I forgot to give you the answer choices. @Ahmad1

Answer 7

is that alright so far?

Answer 8

I'm trying to figure it out, but I can't.

Answer 9

take the midpoint in both axes , the midpoint in the y-axis between 3 and 7, is 4.5
the midpoint in the x-axis between 3 and 5 is 4
so now, does (4,4.5) seems okay ?

Answer 10

sorry between 2 and 7 **
