Answer:
x =-1
Step-by-step explanation:
![\left \{ {{2y = 6x +10} \atop {y = 2x +4}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7B2y%20%3D%206x%20%2B10%7D%20%5Catop%20%7By%20%3D%202x%20%2B4%7D%7D%20%5Cright.)
replace y by 2x +4 in the first equation
2(2x + 4) = 6x + 10
4x + 8 = 6x + 10
-2x +8 = 10
-2x = 2
x = -1
Answer:
or ![y=\sqrt[3]{8x} -1](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B8x%7D%20-1)
Step-by-step explanation:
To find the inverse, you switch y with x and x with y. Then, you solve for y.
[switch y with x and x with y]
[multiply both sides by 8]
[cube both sides]
[subtract both sides by 1]
or ![y=(8x)^{\frac{1}{3}} -1](https://tex.z-dn.net/?f=y%3D%288x%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%20-1)
