This is just a reflection. Not sure what your question is so I’ll just explain reflections. Reflections are flipping a shape across that certain line. Here, it is the X axis. What I usually do is see how far away each point is away from the (line of reflection) x axis. For example, G is 5 points away from the x axis, so the reflection of G is also 5 points away from the x axis. This works with any point of the shape. Hope this helped!
I believe it's not a function because the input (x) 4 has two outputs(y), 2 and 8.
<em>Note: I am assuming the first equation is:</em>
<em>x+y = 3</em>
Answer:
The solution to the system of equations is:
(x, y) = (-2, 36)
Therefore, the x-coordinate of the solution of the system
x = -2
Step-by-step explanation:
Given the system of equations
![\begin{bmatrix}x+y=34\\ x-y=-38\end{bmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bbmatrix%7Dx%2By%3D34%5C%5C%20x-y%3D-38%5Cend%7Bbmatrix%7D)
subtracting the equations
![x-y=-38](https://tex.z-dn.net/?f=x-y%3D-38)
![-](https://tex.z-dn.net/?f=-)
![\underline{x+y=34}](https://tex.z-dn.net/?f=%5Cunderline%7Bx%2By%3D34%7D)
![-2y=-72](https://tex.z-dn.net/?f=-2y%3D-72)
solve -2y for y
![-2y=-72](https://tex.z-dn.net/?f=-2y%3D-72)
Divide both sides by -2
![\frac{-2y}{-2}=\frac{-72}{-2}](https://tex.z-dn.net/?f=%5Cfrac%7B-2y%7D%7B-2%7D%3D%5Cfrac%7B-72%7D%7B-2%7D)
![y=36](https://tex.z-dn.net/?f=y%3D36)
For x+y=34 plug in y = 36
![x+36=34](https://tex.z-dn.net/?f=x%2B36%3D34)
Subtract 36 from both sides
![x+36-36=34-36](https://tex.z-dn.net/?f=x%2B36-36%3D34-36)
Simplify
![x=-2](https://tex.z-dn.net/?f=x%3D-2)
Thus, the solution to the system of equations is:
(x, y) = (-2, 36)
Therefore, the x-coordinate of the solution of the system
x = -2
