The sum of the square of a number and seven times another number is equal to 70.
\n" ); document.write( "x^2 + 7y = 70
\n" ); document.write( "7y = 70 - x^2
\n" ); document.write( "y = $\"%28%2870-x%5E2%29%29%2F7\"$

\n" ); document.write( "This occurs when x=6 then y=4.86 (green line)
\n" ); document.write( " Find the two numbers that achieve this minimum value.
\n" ); document.write( "6 - 4.86 = 1.14 is minimum difference \n" ); document.write( "
