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.
From Section 3.7 Graphing Linear Inequalities. Definition:A linear inequality in two variables x and y is an inequality which can be written as. Ax + By < C, Ax + By > C, Ax + By = C, or Ax + By = C. Definition: A point (x, y) is a solution of an inequality in two variables if the coordinates satisfy the inequality. Definition: The collection of all solutions of an inequality is called the solution set of the inequality. Definition: The graph of an inequality is the set of points which are solutions of the inequality. (That is, the graph is the set of all points whose coordinates satisfy the inequality).
