The definition of an inverse of a function is "the set of ordered pairs obtained by interchanging the first and second elements of each pair in the original function."
This means too find the inverse of a function using ordered pairs, switch the x- and y-coordinates.
This means that (-3, 9) goes to (9, -3); (-1, 1) goes to (1, -1); (0, 0) goes to (0, 0); and (2, 4) goes to (4, 2).
There are no constants here. But we have x and y here. We will create an equation which is: 2y+3x=54. But we will also create a second equation which states the number of seats. x+y=24.
Now we do the two-equation solving method. 2y+3x=54 -2(x+y=24)
2y+3x=54 -2x-2y=-48
x=6
To solve for y, plug in x into one of the original equations. Which one doesn't matter.
Answer: Noah's mixture would be more flavorful and fizzy because his ratio of water and fizz powder aren't to off (not a large ratio gap). Andre's orange fizz would be a little more watered down making it less fizzy and less flavorful because 8 cups were added instead of 6 or 7 cups of water. Also Noah would have less drink made them Andre because he only used 6 cups of water.
