* \"F varies as x\" means F = kx\r
\n" ); document.write( "\n" ); document.write( " * \"F varies jointly as x and y\" means F = kxy\r
\n" ); document.write( "\n" ); document.write( " * \"F varies as x + y\" means F = k(x + y)\r
\n" ); document.write( "\n" ); document.write( " * \"F varies inversely as x\" means F = k/x
\n" ); document.write( ".
\n" ); document.write( "Your problem:
\n" ); document.write( " if x varies inversely as y and x=2 when y=8 find x when y=17
\n" ); document.write( ".
\n" ); document.write( "From: \"x varies inversely as y\" we get
\n" ); document.write( "x = k/y
\n" ); document.write( ".
\n" ); document.write( "to find 'k' use \"x=2 when y=8\"
\n" ); document.write( "x = k/y
\n" ); document.write( "2 = k/8
\n" ); document.write( "16= k
\n" ); document.write( ".
\n" ); document.write( "Our relation is now:
\n" ); document.write( "x = 16/y
\n" ); document.write( ".
\n" ); document.write( "Now, we can answer: find x when y=17
\n" ); document.write( "x = 16/y
\n" ); document.write( "x = 16/17 (this is your answer)\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
