What is the midpoint between the two points (-5, 4) and (3, -8)?

   Midpoint (xM, yM)  =  (4, 5)

Step-by-step explanation:

Coordinates (xA, yA)  

-5  4

Coordinates (xB, yB)  

3   -8

The attachement is not the anwser to your question (anwser above) for showing you how to do it for other questions like that :)

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

step-by-step explanation:

the first one, all those points on the line just make a strait line.
