suppose that x and y vary inversely,
\n" ); document.write( "x = $\"k%2Fy\"$
\n" ); document.write( " and x=7 when y=11.
\n" ); document.write( "7 = $\"k%2F11\"$
\n" ); document.write( "11*7 = k
\n" ); document.write( "k = 77
\n" ); document.write( " write the function that models the inverse variation.
\n" ); document.write( "x = $\"77%2Fy\"$
\n" ); document.write( " then find y when x=10
\n" ); document.write( "10 = $\"77%2Fy\"$
\n" ); document.write( "10y = 77
\n" ); document.write( "y = $\"77%2F10\"$
\n" ); document.write( "y = 7.7 \n" ); document.write( "

\n" );
