You can put this solution on YOUR website!
If y varies inversely as x
\n" ); document.write( " y = k/x
\n" ); document.write( "where k is the constant of variation.
\n" ); document.write( "To find k use information given
\n" ); document.write( " y = k/x
\n" ); document.write( " 5 = k/3
\n" ); document.write( " k = 15
\n" ); document.write( "y = 15/x
\n" ); document.write( " 15 = 15/x
\n" ); document.write( " x = 15/15
\n" ); document.write( " x = 1
\n" ); document.write( "Hope this helps.
