Find the midpoint of the segment joining the points (7,-4) and (9,4).
a). (8,0)
b). (2,-8)
c). (0,2)
d). (0,8)
e). (-8,0)

Jus take the average
so
the midpoint of
(x1,y1) and (x2,y2) is
((x1+x2)/2,(y1+y2)/2)
basically average the x and y terms

so
(7,-4) and (9,4)
average of 7 and 9 is 8
average of -4 and 4 is 0
(8,0) is the midpoint

A

Its equal to d=7.07in

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
