Question

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

Answer 1

Answer:

(3.5, 9)

Step-by-step 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

Answer:

x=5

Solution,

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

By using mid point formula:

$(4 ,11) = ( \frac{x + 3}{2} ,\frac{y + 7}{2} ) \\ 4 = \frac{x + 3}{2} \\ or \: 4 \times 2 = x + 3(cross \: multiplication) \\ or \: 8 = x + 3 \\ or \: - x = 3 - 8 \\ or \: - x = - 5 \\ x = 5$

hope this helps...

Good luck on your assignment..
