M is the midpoint of point A (5,4) and point B (15,0)

What is the x- coordinate of M

x = 10

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( , )

Here (x₁, y₁ ) = A(5, 4) and (x₂, y₂ ) = B(15, 0) , then

M = ( , ) = ( , ) = (10, 2 )

The x- coordinate of M = 10

just get this app called photo math it should be able to do those
