Question

Need a quick answer This is a not graded timed practice testwhat is the answer. Question 3

Answer 1

Since y and x are inversely related, we can write,

`y=(k)/(x)`

then, the constant of proportionality k is given by

`k=y\cdot x`

By substituting the given values, we have

`\begin{gathered} k=4*20 \\ k=80 \end{gathered}`

So the relation is given by

`y=(80)/(x)`

Then, the answer is the second option
