Question
If $p$ and $q$ vary inversely, and $p=10$ when $q=-4,$ what is $q$ when $p=-2 ?$$$\begin{array}{lllll}{\text { F. } 20} & {\text { G. } \frac{4}{5}} & {\text { H. }-\frac{4}{5}} & {\text { 1. }-20}\end{array}$$
Step 1
This means that the product of $p$ and $q$ is a constant. We can write this relationship as $pq = k$, where $k$ is the constant of variation. Show more…
