Answer:
solution and quadratic regression
Step-by-step explanation:
F(x)=7-3x g(x)=3x-7
First let’s solve for f(1)
f(1)= 7-3(1)
f(1)= 7-3
f(1)= 4 *we will save this for later
Let’s now solve for g(1)
g(1)= 3(1)-7
g(1)= 3-7
g(1)= -4
Now we can find f(1) + g(1)
f(1) =4 and g(1)= -4
4+(-4) = 0
Answer:
24
Step-by-step explanation:
We have a system of equations, so we can start with the second equation:
And move y to the other side to isolate x:
Now we can replace x into the first equation:
Notice that we can cancel out the y squared terms:
Now we just need to find x by replacing y into the second equation:
And finally, add them:
