Remember that, although it may look intimidating, (f+g)(x) is simply f(x) + g(x)
Therefore:
(f+g)(x) = f(x) + g(x) Substitute the functions for f(x) and g(x)
(f+g)(x) = (2x² + 1 )+ (x² - 7)
Notice that we first want to write the functions in as parenthesis before we add them. This helps us keep from getting confused on what signs to give each term.
(f+ g)(x) = 2x² + x² + 1 - 7 Collect like terms
(f + g) (x) = 3x² - 6

The answer to your question is 18810
Answer:
There is no solution to the equation.
Step-by-step explanation:
In order to solve the system by substitution, we need to solve the second equation for x.
x - 2y = -8
x = 2y - 8
Now that we have that, we can put that in for x in the other equation and solve for y.
3x - 6y = -12
3(2y - 8) - 6y = -12
6y - 16 - 6y = -12
-16 = -12
No solution
