Answer:
the A is right
Step-by-step explanation:
We have (f+g)(x) = f(x) +g(x)
So f(x) + g(x) = 3x^2 + 2x – 1 and we know g(x) = 2x -2
or f(x) + 2x-2 = 3x^2 + 2x – 1
f(x) = 3x^2 + 2x – 1 - ( 2x -2)
f(x) = 3x^2 + 2x – 1 - 2x +2 \
finally
f(x) = 3x^2 + 1, and the A is right.
Have a good day
Answer:
All real numbers, x ≠ -6
Step-by-step explanation:
Answer:
Equation: 3x + 7 = 16
Unknown Number: 3
Step-by-step explanation:
You must first develop an equation representing this problem:
3x + 7 = 16
Then, you can solve for the unknown number.
3x + 7 = 16
3x = 9
x = 3
13-5 is how you would do this so your answer would be 8 :)
