Domain: All real numbers or (-infinity, infinity)
Range: [-8, infinity)
Answer:
(-6,8)
Step-by-step explanation:
We are given that
![2x+3y=12](https://tex.z-dn.net/?f=2x%2B3y%3D12)
The solution of equation is (_,8).
We have to find the missing value in the solution to the equation.
To find the missing value we will substitute y=8 in equation
Substitute y=8
![2x+3(8)=12](https://tex.z-dn.net/?f=2x%2B3%288%29%3D12)
![2x+24=12](https://tex.z-dn.net/?f=2x%2B24%3D12)
![2x=12-24](https://tex.z-dn.net/?f=2x%3D12-24)
![2x=-12](https://tex.z-dn.net/?f=2x%3D-12)
![x=\frac{-12}{2}=-6](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-12%7D%7B2%7D%3D-6)
Hence, the solution of equation is (-6,8).
The equivalent expression would be 6-16y
Answer: The value of y is 8
Step-by-step explanation:
Since we know x=2 we can sub in 2 for x in the equation
y=2(2)+4
y=4+4
y=8
