If f(x) = 2x - 6 and g(x) = 3x + 9, find (f+g)(x)
valina [46]

Answer:

(f+g)(x)  =  5x + 3

Step-by-step explanation:

f(x) = 2x - 6 and g(x) = 3x + 9, find (f+g)(x)

(f+g)(x) = f  + g  =  (2x - 6)  + (3x + 9) =   5x + 3

(f+g)(x) = f  + g  =  5x + 3

How would you solve this problem 2/6×3= would you divide or multiply
Rainbow [258]
In the order of operation, multiplying or dividing don't take preference over the other. So with them, you work from left to right.

This means for this question, you first divide, then multiply.
