Question

3.
If the mid point of (x, 5) and (2, 3) is (4,4), then the value of 'x' is
a) 4
b) 2
c) 6
​

Answer 1

Answer:

A = (x,5)

B = (2,3)

mid point = (4,4)

4 =( x+2)/2

8 = x + 2

x = 6

Answer 2

Answer:

using mid pont formula

X=4 and Y=4

x1=x ,y1=5

x2=2 and y2=3

(X,Y)=(x2+x1)/2 ,(y2+y1)/2

(4,4)=(2+x)/2,(3+5)/2

(note≈all ys are given and we have to find x so we neglat y)

4=(2+x)/2

4×2=2+x( by cross multiplication)

8=x+2

x+2=8

x=8-2

x=6
