Hey I was presented with a math problem and im pretty lost I was wondering if anybody could lend a helping hand,

If R varies inversely as S, when S is doubled, R is multiplied by...







If anybody knows how to attack this problem your help is greatly appreciated!

This is what I'm thinking:

\(\displaystyle \begin{array}{l}
\frac{R}{1} = \frac{1}{S}{\rm } \Leftarrow {\rm inverse relationship} \\
\\
{\rm To double S, you must multiply both sides by }\frac{{\rm 1}}{{\rm 2}} \\
\frac{R}{2} = \frac{1}{{2S}} \\
\end{array}\)

So you divide R by 2 ( or multiply by 1/2)

look in the FAQ, you have to download teXaide and write the equations in there, then cut and paste in here with TeX "tags".
