Corner points of the feasible region determined by the system of
linear constraints are $A\left(0,5\right),B\left(6,8\right),C\left(6,0\right),D\left(3,0\right)$ $E$ $\left(0,2\right)$
$let2=px+9y$ where p, $9>0$ 0 be the objective function.
$\left(i\right)$ Find $p,$ $9$ so that minimum of $z$ occurs at two points D, E and it's
maximum value is $72$ at the point $B$
$\left(ii\right)$ How many solutions are there in the given L.P.P. ?
$\left(ii\right)$ Find the constraint which forms the boundary
DE of the feasible region.
$\left(iv\right)1$ $|s\left(3,2\right)$ a point of the feasible region ?
