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.
The dark line represents all the numbers that satisfy xâ¤2. If we pick any number on the dark line and plug it in for x, the inequality will be true. The following graph represents the inequality. Note that the open circle on 2 shows that 2 is not a solution to.Here are the graphs of and xâ¥2, respectively: An inequality with a  â   sign has a solution set which is all the real numbers except a single point (or a number of single points).Thus, to graph an inequality with a  â   sign, graph the entire line with one point removed. For example, the graph of xâ 2 looks like:Graph of the Inequality xâ¤2.n inequality with a  â   sign has a solution set which is all the real numbers except a single point (or a number of single points). Thus, to graph an inequality with a  â   sign, graph the entire line with one point removed.
