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).
Answer:
Hi! I'm not sure if I'm doing your question correctly, but 12×(-7)= -84.
so, if this is what you meant, it would be negative
Answer:
g(5) = 21
Step-by-step explanation:
Substituting f(x) into g(x):
g(x) = 2(3x-4) - 1
= 6x - 8 - 1
= 6x - 9
Seeing that g(x) = 6x-9,
g(5) = 6(5) - 9
= 30 - 9
= 21

Answer:
f(-12) = 74
Step-by-step explanation:
You first plug in the number into all of the x's. In this case, we get f(-12)=-8(-12)-22.
The simplify.
f(-12)= 96-22
f(-12)= 74
