Answer:
G = (2, 9)
Step-by-step explanation:
The midpoint is the average of the endpoints, so we have ...
M = (G+H)/2
Solving for G gives ...
G = 2M -H = 2(5, 9) -(8, 9) = (10-8, 18-9)
G = (2, 9)
Answer:
x = 5
y = -1.25
Step-by-step explanation:
3x+4y=10
3x-4y=20
----------------
6x=30
x=5
3(5)-4y=20
15-4y=20
-4y=5
y=-1.25
