Answer:

  (1/2, -1)

Step-by-step explanation:

The midpoint is the average of the end points:

  M = (R + S)/2 = ((4, -7) + (-3, 5))/2 = ((4-3)/2, (-7+5)/2) = (1/2, -2/2)

  M = (1/2, -1)

I will show you how to do first one but it is simple addition and subtraction.

7y + 5 + (3 - y)

We just combine like terms
7y - y + 5 + 3

6y + 8

I will do the second one for subtraction
5 + 5q - (3q - 9)

since the subtracroon sign is outsiDr patenthesis you have to apply it to both terms
5 + 5q - 3q + 9

since it was -9 it became --9 which is +9
so:
5q - 3q + 5 + 9

2q + 14
