Answer:
2. (1.5, 1.5)
Step-by-step explanation:
midpoint = (x1+x2)/2 , (y1+y2)/2
A = (-3,-3) and B = (6,6)
midpoint = (-3+6)/2, (-3+6)/2
= 3/2 , 3/2
Answer:x=2, y=3
Step-by-step explanation:
solving this equation simultaneously
-9x - 2y=-12.............(1)
2x + 5y=-11.. ...........(2)
Using elimination method
Multiply equation 2 by 2 and equation 1 by 5
-45x -10y= -60...........(3)
4x + 10y=-22...............(4)
Subtracting equation 2 from 1
-41x + 0=-82
41x=82
x=82/41
X=2
To find y put x in equation 1
-9x - 2y= -12
-9(2)-2y=-12
-18-2y=-12
-2y=-12+18
-2y=6
Y= 6/2
Y=3
X=2, Y=3
