Answer: 4
Step-by-step explanation:
The procedure is pretty basic. First you have to substitute what you know in the equation. So as you know f(x)=18, just substitute f(x) by 18, leaving it like 18 = 3x + 6.
Then you have to start to move things around. First start with the + 6 that is adding, so it moves to the other side as a substraction giving 18 - 6 = 3x -> 12 = 3x. The next step is to get rid of that 3, so because it's multiplying the x, it moves to the other side as a division leaving you with 12 ÷ 3 = x -> 4 = x. There you have the answer! For a value/y of 18 in that function, the x is 4
The answer is D.
F(x) = y is basically what you are looking for. You substitute x for x and find if it matches with Y. D is the only answer where the ordered pair (-6, 10) ,matches up with F(x) = y.

Answer:
75/4 cups (or 18-3/4 cups)
Step-by-step explanation:
Ignore all the wording about glue, baking soda and saline.
What this question reduces to is that the recipe for :
2 people ---> requires 3 3/4 cups (or 15/4 cups) of shaving cream
10 people ----> requires 5 times the amount of shaving cream needed for 2 people
Hence shaving cream needed for 10 people
= 5 x 3 3/4 cups
= 5 x 15/4 cups
= 75/4 cups (or 18-3/4 cups)
