Answer:
A. -45
Step-by-step explanation:
multiplying a positive an a negative number gives out a negative result
so when we multiple 9 with -5 the result is -45
6x-3
You have to put f(x) into g(x) to find the answer, so you rewrite it like this: 3(2x-1)
Answer: B
Step-by-step explanation:
(f/g) means to divide f(x) by g(x).

To find the domain, you set the domain equal to zero and solve for x.
3x-5=0 [add both sides by 5]
3x=5 [divide both sides by 3]
x=5/3
Now, we know that B is the correct answer.
