Question

SOMEONE HELP ME WILL GIVE 30 POINT PLUS BRAINLIEST!!!

Answer 1

Answer:

1. 16

2. 4

3. x = 11

4. (-2, 5)

5. (-10, -5.5)

Step-by-step explanation:

1. Because Q is the midpoint, PQ + QS = PS, and PQ = QS

PQ = 8, so QS = 8

8+8 = 16 = PS

2. QS = 8, and R is the midpoint, so QR is half

8/2 = 4, QR = 4

3. PQ = QS (because Q is the midpoint of PS)

3x - 4 = 29

3x = 33

x = 11

4. midpoint formula: add the two x coordinates, then divide by 2 to get the x coordinate, add the two y coordinates and divide by 2 to get the y coordinate

x coordinate: $\frac{-9+5}{2} = -2$

y coordinate: $\frac{3+7}{2} = 5$

(-2, 5)

5. Use the midpoint formula again

x coordinate: $\frac{-12+-8}{2} =-10$

y coordinate: $\frac{-7+-4}{2} =-5.5$

(-10, -5.5)
