<PRE><B>Question 30517</B>
 am doing Linear Programming and need help with finding the vertecies so i can find the odjective functions. This is what my problem looks like:

Find the Maximum and minimum values if they exist of C=3x+4y for each set of constrainst.

{{{ 3&lt;x&lt;8 }}}
{{{ 2&lt;y&lt;6 }}}
{{{2x+y&gt;12 }}} 
PLOT GRAPHS FOR ALL LIMITING VALUES TAKING THEM AS EQUAL TO SIGNS...THAT IS 
{{{ graph( 600, 600, -2, 10, -2, 10, (x-3)/0.00001,(x-8)/0.00001,2,6,12-2*x) }}}
 YOU CAN SEE FROM THE GRAPH THAT THE VERTICES ARE (3,2),(3,6) AND (5,2)...HOPE YOU CAN CONTINUE FROM HERE..
