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.
An inequality is like an equation that uses symbols for less than(<) and greater than(>) where an equation uses a symbol for is equal to (=). So where the equation: X = Y + 5 says that X is equal to Y plus 5, X < Y + 5 says that X is less than Y plus 5, and X > Y + 5 says that X is greater than Y plus 5. Now I have a problem for you: Substitute the ? in the following expression for the correct inequality symbol: 5 ? 4.
