Answer:
C) x = -2
Step-by-step explanation:
Original equation:
![12+\sqrt{1-4x}=15\\](https://tex.z-dn.net/?f=12%2B%5Csqrt%7B1-4x%7D%3D15%5C%5C)
subtract 12 from both sides:
![\implies \sqrt{1-4x}=3](https://tex.z-dn.net/?f=%5Cimplies%20%5Csqrt%7B1-4x%7D%3D3)
square both sides:
![\implies 1-4x=9](https://tex.z-dn.net/?f=%5Cimplies%201-4x%3D9)
subtract 1 from both sides:
![\implies -4x=8](https://tex.z-dn.net/?f=%5Cimplies%20-4x%3D8)
divide both sides by -4:
![\implies x=-2](https://tex.z-dn.net/?f=%5Cimplies%20x%3D-2)
The midpoint is (5, ¹/₂).

Further explanation</h3>
The midpoint is the coordinates of a point right in the middle of a line segment or two endpoints.
The Midpoint Formula ![\boxed{\boxed{ \ M = \bigg( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \bigg) \ }}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cboxed%7B%20%5C%20M%20%3D%20%5Cbigg%28%20%5Cfrac%7Bx_1%20%2B%20x_2%7D%7B2%7D%2C%20%5Cfrac%7By_1%20%2B%20y_2%7D%7B2%7D%20%5Cbigg%29%20%5C%20%7D%7D)
So, abscissa and ordinate of the midpoint are the averages of both endpoints. i.e., (x₁, y₁) and (x₂, y₂).
Given (x₁, y₁) = (5, 4) and (x₂, y₂) = (5, -3).
Let's calculate the midpoint.
![\boxed{ \ M = \bigg( \frac{5 + 5}{2}, \frac{4 + (-3)}{2} \bigg) \ }](https://tex.z-dn.net/?f=%5Cboxed%7B%20%5C%20M%20%3D%20%5Cbigg%28%20%5Cfrac%7B5%20%2B%205%7D%7B2%7D%2C%20%5Cfrac%7B4%20%2B%20%28-3%29%7D%7B2%7D%20%5Cbigg%29%20%5C%20%7D)
![\boxed{ \ M = \bigg( \frac{10}{2}, \frac{1}{2} \bigg) \ }](https://tex.z-dn.net/?f=%5Cboxed%7B%20%5C%20M%20%3D%20%5Cbigg%28%20%5Cfrac%7B10%7D%7B2%7D%2C%20%5Cfrac%7B1%7D%7B2%7D%20%5Cbigg%29%20%5C%20%7D)
![\boxed{ \ M = \bigg( 5, \frac{1}{2} \bigg) \ }](https://tex.z-dn.net/?f=%5Cboxed%7B%20%5C%20M%20%3D%20%5Cbigg%28%205%2C%20%5Cfrac%7B1%7D%7B2%7D%20%5Cbigg%29%20%5C%20%7D)
We get the midpoint between the two endpoints, that is, (5, ¹ / ₂).
