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.
A linear inequality in two variables takes the form y > mx+b or y. Linear inequalities are closely related to graphs of straight lines; recall that a straight line has the equation y =mx + b. The solution to a linear inequality includes all the points in one half of the plane.
