Given f(x)=x+9 and g(x)=5x , what is f(3)+g(-3) ?

-3

3

-27

27

f(x)=x+9

f(3) = 3 + 9 = 12

Now, g(x) = 5x

g(-3) = 5(-3) = -15

So, f(3)+g(-3)  = 12 - 15 = -3

In short, Your Answer would be: Option A

Hope this helps!

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
