If you multiply or divide both sides of an inequality by a number you need to reverse the inequality sign?
negative flip
Do you only flip the inequality when you divide by a negative number?
Yes you do, you also flip the inequality sign if you multiply by a negative # The > and < signs are strictly the "Greater than" and "Less than" signs. The inequality sign is an = with a / stroke through it. If you divide an inequality by -1 it remains an inequality.
What are the properties in solving equations and inequations?
You can add, subtract, multiply, or divide both sides of the equation or inequality by the same number. Don't multiply or divide by zero. In the case of an inequality, if you multiply or divide by a negative number, the sign of the inequality must be reversed. E.g., if you multiply both sides by -2, a "less-than" sign should be replaced by a "greater-than" sign.
Does an inequality sign change in an equation when both sides are multipled or divided by negative number?
The sign changes if you multiply/divide by a negative number. It stays the same if you add/subtract by a negative number.
When you multiply or divide both sides by a negative number then switch the direction of the?
The relation = , is less than, is greater than inequality sign
When you have to reverse the inequality sign?
The usual case is when you multiply or divide an inequality by a negative number.
What must occur in a linear inequality when you divide or multiply by a negative number?
The inequality sign must be flipped.
If you multiply or divide both sides of an inequality by a number you need to reverse the inequality sign?
negative flip
When you must reverse the inequality sign?
When solving an inequality, you must revers the inequality sign when you multiply (or divide) both sides by a negative number.
If you multiply or divide both sides of an inquality by a negative number you need to?
Change the direction of the inequality.
Do you flip the sign of this inequality 8x plus 4y12?
Only when you multiply or divide by a negative number

What happens if you multiply or divide an inequality by a negative number?
The inequality sign changes direction. So 2<3 Multiply by -2 and you get -4>-6 (similarly with division).

What happens when you multiply or divide an inequalitie 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
What happens to the inequality symbol when you subtract a negative number?
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.
