\n" ); document.write( "\n" ); document.write( "If \"y\" varies inversely as \"x%7D%7D%5D%2Cthen+we+have+%7B%7B%7Bk\" such that \"y=k%2Fx\".\r
\n" ); document.write( "\n" ); document.write( "if the variation, \"y=9\", when \"x=3\", than we have\r
\n" ); document.write( "\n" ); document.write( "\"9=k%2F3\"=>\"9%2A3=k\"=>\"k=27\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, general formula to describe the variation will be:\r
