If f(x)= 10x + 3 and g(x)= x+15, find (f-g)(x)

Question

can you please help me with this math problem if you can please show work help help

Answer 1

(f-g) (x) is just f(x) - g(x). 10x+3 - (x+15).

Distribute the negative to subtract both terms of g(x): 10x +3 -x -15

And combine like terms: 10x +3 -x -15 = 9x-12

I hope this helps, and have fun mathing!
