Question

If the midpoint between (x, 3) and (9, 9) is (7, 6), find the value of x.?

Answer 1

x+9/2=7

Answer 2

It said midpoint of those two points is (7,6)
x + 9/2 = 7 (x2 - x1/2, y2 - y1/2) is mid point formula

x + 9 = 14

hope u get from there

Answer 3

i dont get it at all

Answer 4

sorry I worte the formula wrong

Answer 5

Midpoint of two points is given by ((x2 + x1)/2 , (y2 + y1)/2)

Answer 6

@zpupster 7 is not an answer

Answer 7

so here x1 = x and x2 = 9 given midpoint x - cordinate is 7

now according to the formula (9 + x)/2 = 7

Answer 8

ok you have to solve for x

first mult both sides by 2

x+9/2*2=7*2
x + 9 = 14 then subtract both sides by 9
x+9-9 =14-9

x=5

Answer 9

9 +x = 14

x = 14 - 9

x = 5

Answer 10

thank u

Answer 11

i did not say 7 is the answer i plugged the numbers in the midpoint formula
