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.
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.
