You can put this solution on YOUR website!
You can express this indirect (inverse) variation as:
\n" ); document.write( " $\"y+=+k%2Fx\"$ where k is called the constant of variation.
\n" ); document.write( "To find the value of k, substitute the given y = 10 and x = 25.
\n" ); document.write( " $\"10+=+k%2F25\"$ Multiply both sides by 25.
\n" ); document.write( " $\"k+=+250\"$ So now you have...
\n" ); document.write( " $\"y+=+250%2Fx\"$ and if you substitute x = 35, you can find the corresponding value of y.
\n" ); document.write( " $\"y+=+%28250%2F35%29\"$ Evaluate.
\n" ); document.write( " $\"highlight%28y+=+7.143%29\"$ \n" ); document.write( "

\n" );
