Answer:
![0\leq x < infinite](https://tex.z-dn.net/?f=0%5Cleq%20x%20%3C%20infinite)
Step-by-step explanation:
we have
![y=\sqrt{x} +4](https://tex.z-dn.net/?f=y%3D%5Csqrt%7Bx%7D%20%2B4)
Find out the domain
we know that
The radicand must be greater than or equal to zero
so
![x\geq 0](https://tex.z-dn.net/?f=x%5Cgeq%200)
The domain is the interval -----> [0,∞)
All real numbers greater than or equal to zero
![0\leq x < infinite](https://tex.z-dn.net/?f=0%5Cleq%20x%20%3C%20infinite)
If B is the midpoint of AC, then AB=BC. It is also BC=AC-AB
AB = x + 6
AC = 5x - 6
BC = (5x - 6) - (x + 6)
We can kinda use distributive property, like this:
BC = 5x - 6 -x - 6
Combine like terms:
BC = 4x - 12
To verify, we can add AB and BC to see if their sum is equal to AC.
(x + 6) + (4x - 12) = 5x - 6
If we are correct, this equation will be true.
x + 6 + 4x - 12 = 5x - 6
Combine like terms:
6 + 5x - 12 = 5x - 6
5x - 6 = 5x - 6
It's correct!
BC = 4x - 12. Final Answer.

<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
On a graph, the solution of a system of equations is given by the intersection between the curves. In this graph, the intersection of the two curves happen close to x = -3.25, y = 2.5, hence the solution is approximated by:
D. ![\left(-\frac{13}{4}, \frac{5}{2}\right)](https://tex.z-dn.net/?f=%5Cleft%28-%5Cfrac%7B13%7D%7B4%7D%2C%20%5Cfrac%7B5%7D%7B2%7D%5Cright%29)
