-3x + 7 < -3
-3x < 4
x > -(4/3) ■
Always.
No. Only flip the inequality when multiplying or dividing by a negative number.
When an inequality is multiplied or divided by a negative number the inequality sign is reversed.Example : -x < 7 ......after multiplying by (say) -2 this becomes 2x > -14
Flip it around
When an Inequality expression is multiplied (or divided) by a negative number then the Inequality sign is reversed. Example : -9x < 18 : -x < 2 : x > -2........as both sides have been multiplied by -1.
The inequality is "flipped" when multiplied by a negative number. For example, if x > y and a is a negative number, then ax < ay.
No, you only flip the inequality sign if you are dividing by a negative number on both sides of the inequality
Always.
The usual case is when you multiply or divide an inequality by a negative number.
No. Only flip the inequality when multiplying or dividing by a negative number.
When one side of the inequality is divided or multiplied by a negative number.
When an inequality is multiplied or divided by a negative number the inequality sign is reversed.Example : -x < 7 ......after multiplying by (say) -2 this becomes 2x > -14
When you divide both sides of an inequality by a negative number, the inequality sign flips.
The inequality symbol doesn't change direction in this case.Note that that is the same as adding a positive number.Note also that if you MULTIPLY or DIVIDE by a negative number, then you need to change the direction of the inequality symbol.
In the case of an inequality, if you mulitply by a negative number, you have to reverse the direction of the inequality. E.g.: -x < 10 becomes: x > -10 (Here, I multiplied by -1, and simultaneously reversed the direction of the inequality.)
The sign changes if you multiply/divide by a negative number. It stays the same if you add/subtract by a negative number.
Yes.
