Step-by-step explanation:
solution,
midpoint between A(-1,4) and B(-5,-2)=
(X1 + X2 ÷2, Y1 + Y2 ÷2)
=(-1-5÷2 , 4-2)
=(-6÷2 ,2÷2)
=(-3 , 1)
therefore the midpoint between A(-1,4) and B(-5 ,-2)=(-3,1)
Answer:
15-12+5.5+3-8
15-12=3
3+5.5=8.5
8.5+3=11.5
11.5-8=3..5
sorry i am struggling the same
2+2=4
U=19
A=8
B=5
