The problem does not specify whether it is a proportional variation or an inversely proportional variation, so both cases will be solved.
<u>case a) proportional variation</u>
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
<u>Find the value of k</u>
<u>Find the value of y for x=</u>
<u>the answer case a) is</u>
<u>case b) inverse variation</u>
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
<u>Find the value of k</u>
<u>Find the value of y for x=</u>
<u>the answer case b) is</u>
