Let f(x) = -5x - 4 and g(x) = 6x - 7. Find f(x) + g(x)
A. x + 3
B. x - 11
C. -11x = 3b
D. -11x - 11
C?
f+g = (-5x-4)+(6x-7) = (-5+6)x + (-4-7) = x-11
Bzzzt. Looks like B
LOL thank you
To find f(x) + g(x), we need to add the two functions together.
f(x) = -5x - 4
g(x) = 6x - 7
To find f(x) + g(x), we can directly add the corresponding terms:
f(x) + g(x) = (-5x - 4) + (6x - 7)
Now we can simplify by combining like terms:
f(x) + g(x) = -5x + 6x - 4 - 7
Combining the x terms and the constant terms, we get:
f(x) + g(x) = (6x - 5x) + (-4 - 7)
= x - 11
Therefore, the answer is B. x - 11.
