F(x) is another way of saying "y". Just that it's saying the "function of x".
The additive inverse is a number, when added to another number, yields 0.
Its basically the opposite number.....same number, different sign.
so if the number m and 58 are additive inverses, then m = -58 <==
because -58 + 58 = 0

120 people who all need 1 drink, so if each drink needs .5 cups of concentrate you will do 120d × 0.5 = 60 total cups of concentrate. if you then set up a fraction, you could cross multiply to get the answer, but I cant do fractions here so I'll say this: if every 5 cups of concentrate gives 19 cups of water, then you divide 60 cups by 5 cups to see how many "batches" of this recipie you will need, you get 12 batches, so 12 x 19 (cups of water per batch) to get 218 ( I think, check my math with a calculator
