When Do You Flip The Sign In An Inequality
Olivia Luz
1 the inequality sign changes when both sides are multiplied by a negative number.
Multiplying by capacity of 2 you get 20 12 dividing by capacity of 2 you get 5 3 in case you multiply or divide by capacity of a good variety the sign do no exchange. 10 6. 3 4 a 21. Now it s a rule of thumb to flip the inequality when you multiply both sides by a negative number but you don t even need to use multiplication to see why this is the case.
For instance if we were solving the inequality 2. When you multiply or divide both sides of the inequality by a negative number you can flip the sign. For example if you have 2x 8 and divide both sides by 2 you end up with. To solve you need to get all the x es on the same side of the inequality.
You flip the inequality sign when you are dividing or multiplying both sides by a negative you also flip the inequality sign when you swap the answers on both sides the other time you flip the. If you do not flip the sign it will not be a true inequality. Multiplying and dividing inequalities by negative numbers. Anytime we multiply or divide both sides of the inequality by a negative we must flip the inequality sign meaning we must reverse its direction.

However if you multiply by a positive number you do not need to change the inequality sign. This happens because it needs to read true.Flip the inequality sign when you multiply or divide both sides of an inequality by a negative number. You also often need to flip the inequality sign when solving inequalities with absolute values. Multiplying by capacity of two you get 20 12 dividing.
