Answer:
-1
Explanation:
To find the x-coordinate of the midpoint M between points A(3, -6) and B(-5, 0), we can use the midpoint formula:
Midpoint formula:

Let's apply this formula to find the x-coordinate of M:
x-coordinate of,

Given that A(3, -6) and B(-5, 0),
we can substitute the values into the formula:
x-coordinate of M = (3 + (-5)) / 2
= (-2) / 2
= -1
Therefore, the x-coordinate of the midpoint M is -1.
