Dividing by negative number inequality
WebThe reason this happens is the absolute value always creates a positive number. And, a positive number will never = a negative number. So, let's extend that concept to inequalities. 1) An absolute value < a negative: In this situation, we have a positive value < a negative value. That would always be false. http://mathsteacher.com.au/year9/ch02_linear/13_div_neg/divide.htm

WebSolving inequalities is very similar to solving equations, except you have to reverse the inequality symbols when you multiply or divide both sides of an inequality by a negative number. There are three ways to represent solutions to inequalities: an interval, a graph, and an inequality.
