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 of Graphs of Inequalities. Graphing inequalities on either a number line or in the coordinate plane (with x and y axes) helps to visually represent several forms of inequalities: The graph of a linear inequality produces a region on the coordinate plane with a boundary line. Every point in that region is a solution of the inequality.
