Question

Identify the variation as direct, inverse, joint or combined.
xy = c

Answer 1

guess it is inverse since you can write this as
\[y=\frac{c}{x}\]

Answer 2

Its inverse proportion

Answer 3

x and y are inversely proportional.
Im going to make up numbers and show why.
lets say c = 20
two numbers that multiply to 20 are x = 1, y = 20
another solution is x = 2, y = 10
and also x = 4, y = 5
Notice how one variable goes up (x), the other goes down.
Thats what it means to be "inversely" proportional

Answer 4
