F(x) = 9-3x
g(x) = 5x-7
Find f(x)+g(x).
1 answer:
Answer:
In the problem, the sum of the two functions is 2x + 2
Step-by-step explanation:
For this problem, we have to add together f(x) and g(x).
<em>f(x) = 9 - 3x</em>
<em>g(x) = 5x - 7</em>
(f + g)(x) = (9 - 3x) + (5x - 7)
Combine like terms.
(f + g)(x) = 2x + 2
So, when you combine the two functions together, you will get 2x + 2.

Hope this helps idk if it does tho
3x-12+5-x=2x-7
2x-7 =2x-7
Means there are infinite solutions.
- y^2+9y+20
- y^2+10y+21
- y^2+2y+3
- Step-by-step explanation:
- (y+5(y+4) =y(y+4)+5(y+4) =y^2+4y+5y+20 =y^2+9y+20
- (y+3(y+7) =y(y+7)+3(y+7) =y^2+7y+3y+21 =y^2+10y+21
- (y+3)(y-1)
=y(y-1)+3(y-1)
=y^2-y+3y-3
= y^2+2y+3
