I think it is A, cause the horizontal axis is 4 (x), and the vertical axis is 8 (y)
and then the <= means that it is inside the ellipse
Answer:
x=15
Step-by-step explanation:
Since 13+6+2x-18= 4x-29, use this equation.
Combine like terms:
1+2x= 4x-29
-1 -1
2x= 4x-30
-4x -4x
![\frac{-2x=-30}{-2}](https://tex.z-dn.net/?f=%5Cfrac%7B-2x%3D-30%7D%7B-2%7D)
x=15
Hope this helps! :)
