Question

The midpoint between points (x, y) and (3, 7) is (4, 11). What is x?​

Answer 1

(3.5, 9)

Explanation:

You can quickly find the midpoint by averaging the x and y values separately.

X coordinate: (3+4)÷2=7÷2=3.5

Y coordinate: (7+11)÷2=18÷2=9

The midpoint is then at (3.5,9).

Answer 2

x=5

Solution,

Midpoint between (X,y) and (3,7) is (4,11)

By using mid point formula:

`(4 </em></strong><strong><em>,</em></strong><strong><em>11) = ( (x + 3)/(2) </em></strong><strong><em>,</em></strong><strong><em>(y + 7)/(2) ) \\ 4 = (x + 3)/(2) \\ or \: 4 * 2 = x + 3(cross \: multiplication) \\ or \: 8 = x + 3 \\ or \: - x = 3 - 8 \\ or \: - x = - 5 \\ x = 5`

hope this helps...

Good luck on your assignment..
