Question

I really need help with this please

Let f(x)=2x+4x and g(x)=-6x-7. Find f(x)-g(x)

Answer 1

@ash2326 can you help???

Answer 2

The problem tells you what f(x) = which is (2x+4x) and g(x) is (-6x-7). Then subtract the two.

Answer 3

wait thats all i have to do omg

Answer 4

I would think so. So then its (2x+4x)-(-6x-7)=0

Answer 5

just don't equate it to 0 (=0 )

Answer 6

but wouldn't it be -7, because 2x+4x=6x and 6x-6x=0

Answer 7

nopes, you are not subtracting correctly ....

(2x+4x)-(-6x-7)
distribute the - sign through the 2nd bracket
2x+4x - (-6x) - (-7)

got this ?

Answer 8

so it would be 12x+7?

Answer 9

now you got it! :)
correct.
