This is dullness of hearing.. The word goes in the ears, and comes to the heart, and meets dullness and slowness and hardness. The opposite of dullness of hearing is hearing with faith which produces obedience.
The feasible regions of linear programming are defined by a set of inequalities. In mathematics, an inequality is a relation that holds between two values when they are different (see also: equality). 1  The notation a â  b means that a is not equal to b.
Definition: Additive Property of Inequalities. The additive property of inequalities states that if the same amount is added to both sides of an inequality, then the inequality is still true. Let x, y, and z be real numbers. In symbols, we can say the following: If x y, then x + z y + z. If x y, then x + z y + z.
