You can put this solution on YOUR website!
What we would do is first graph these descriptions onto x y plane:
\n" ); document.write( "\"x%3C=5\", \"y%3E=4\", \"-2x%2B5y%3C=30\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "That will form a planar figure. You would expect the optimal solution to C to be one of the vertices of this planar figure. Test each vertex point, and find which one give the maximum and which gives the minimum.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The first two constraints are simple to graph. The last given constraint may be easiest as slope-intercept form: 5y<=2x+30, into \"y%3C=%282%2F5%29x%2B6\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You would continue with this graph to pick your vertex points:\r
\n" ); document.write( "\n" ); document.write( "\"graph%28300%2C300%2C-7%2C7%2C-1%2C9%2C4%2C%282%2F5%29x%2B6%29\"UNFORTUNATELY, entering x<=5 will not work in this rendering method, so it NEEDS to be included, but is missing.\r
\n" ); document.write( "\n" ); document.write( "Points to check will be (-5,4), (5,4), and (5,8).
\n" ); document.write( "
\n" );
