A feasible region of a system of linear inequalities is said to be ......., if it can be enclosed within a circle.
A feasible region of a system of linear inequalities is said to be bounded, if it can be enclosed within a circle.
A corner point of a feasible region is a point in the region which is the ....... of two boundary lines.
A corner point of a feasible region is a point in the region which is the intersection of two boundary lines.
The feasible region for an LPP is always a ....... polygon.
The feasible region for an LPP is always a convex polygon.
If the feasible region for a LPP is unbounded, maximum or minimum of the objective function $Z=a x+b y$ may or may not exist.
Maximum value of the objective function $Z=a x+b y$ in a LPP always occurs at only one corner point of the feasible region.
