The usual case is when you multiply or divide an inequality by a negative number.


When solving an inequality when do you reverse the inequality sign?

When you divide both sides by a negative value


Is 82 an inequalitie?

No. An inequality must have an inequality sign, for example, "<".


If you multiply or divide both sides of an inequality by a number you need to reverse the inequality sign?

negative flip


What must occur in a linear inequality when you divide or multiply by a negative number?

The inequality sign must be flipped.


How do you solve an inequality when using the distributive property?

You solve an inequality in the same way as you would solve an equality (equation). The only difference is that if you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality sign. Thus, if you have -3x < 9 to find x, you need to divide by -3. That is a negative number so -3x/(-3) > 9/(-3) reverse inequality x > -3


What are the critical features of an inequality?

An inequality must have a greater than sign (>) OR a less than sign (<) OR a greater than or equal to sign (≥) OR a less than or equal to sign (≤).


Explain how solving -7y > 161 is different from solving 7y > -161?

Sample response: Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y


Is xl7.6x7.0 an inequality?

No. To be an inequality, it must somewhere have a greater than, less than, greater-or-equal, or less-or-equal sign.


When you divide both sides of an inequality by a positive value you must change the direction of the inequality sign?

No. Only when you divide by a negative.


How do you solve an inequality in one variable?

It depends on the specific inequality. In the simplest cases, it is solved just like an equation; except that you must be careful when multiplying and dividing - if you multiply or divide both sides by a negative number, you must switch the inequality sign. For instance, a "less-than" sign would be changed to a "greater-than" sign.


How do you know when to reverse the direction of an inequality symbol?

u only reverse the sign when u multiply or divide by a NEGATIVE number...otherwise u don't change the direction
