Answer:
B
Step-by-step explanation:
1) lets use elimination to solve this:
multiply 10x+4y=24 with 3 in order to get "4y" into "12y"
3(10x+4y=24)
30x+12y=72
now subtract both equations to eliminate 'y"
30x+12y=72
-
6x+12y=48
---------------------
24x=24
x=1
now substitute 1 in the above equation:
6(1)+12y=48
6+12y=48
12y=42
y=7/2
Answer:
(6,4)
Step-by-step explanation:
Midpoint=((x1+x2)/2 ,(y1+y2)/2)
((10+2)/2 ,(7+1)/2)
(6,4)
x1=10
x2=2
y1=2
y2=1
