Answer:

7. M = (-1.5,7)

8. (8,4)

9. m<QRS=46°

Explanation:

7. Use the midpoint formula which is (x1+x2/2 , y1+y2/2)

So (-1-2/2 , 9+5/2)

(-3/2 , 14/2)

So M = (-1.5,7)

8. This is one simple if you understand.

Since (-6,6) is the starting end point and (1,5) is the mid point then (8,4) has to be the other end point. -6 to 1 is +7. 1 to 8 is +7. 6 to 5 is -1. 5 to 4 is -1.

9. 3x-8+2x+6=98

5x-2=98

5x=100

x=20

So plug in x for QRS

2(20)+6

40+6

46

Hope this helps
