(6,6)
Step-by-step explanation:
To find the x coordinate of the midpoint take the average of the x coordinates of the endpoints
(10+2)/2 = 12/2 = 6
To find the y coordinate of the midpoint take the average of the y coordinates of the endpoints
(3+9)/2 = 12/2 = 6
(6,6)
ANSWER
X < 9
Solve
2x < - x + 20 + 7
2x < - x + 27 change the signs
2x + x < 27 add the like terms
3x < 27 divide by 3
x < 9
