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.
To graph an inequality, treat the, â¤ , , or â¥ sign as an = sign, and graph the equation. If the inequality is or, graph the equation as a dotted line. If the inequality is â¤ or â¥ , graph the equation as a solid line. This line divides the xy-plane into two regions: a region that satisfies the inequality, and a region that does not. Next, pick a point not on the line. Check to see if this point satisfies the inequality.
