D Each nonempty Question 5 Let PCR be a polyhedron defined by linear equalities and inequalities. A vector ER" is a basic solution of P if there are n constraints of P that are active at x and that are linearly independent. O True O False Question 6 can be represented as the convex hull of its extreme points. The property of being a basic solution depends on the representation (the system of linear equalities and inequalities) that defines a polyhedron. O True O False
