Hypertension is the term used to describe high blood pressure. Blood pressure is a measurement of the force against the walls of your arteries as your heart pumps blood through your body. Blood pressure readings are usually given as two numbers -- for example, 120 over 80 (written as 120/80 mmHg).
well you only switch inequality signs when dividing or multiplying the opposite side of the equation by a negative number because negative numbers can shift or switch around the graph so you have to flip the inequality sign otherwise you'll get the wrong graph. Jayne Â· 1 year ago.
Inequality (mathematics) In mathematics, an inequality is a relation that holds between two values when they are different (see also: equality). The notation a â  b means that a is not equal to b. It does not say that one is greater than the other, or even that they can be compared in size.
