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 inequality sign is when raising both sides to a negative power. e.g. 5>4, but (5^-1)<(4^-1) i.e. 1/5 < 1/4....this is true when both sides of the inequality are either positive or negative, if one side is positive and one side is negative, the inequality sign does not get flipped, e.g. -4<5 and -1/4 < 1/5 (in this case the inequality sign is not flipped)

Do you flip the inequality sign if the only the variable is negative?

No, you only flip the inequality sign if you are dividing by a negative number on both sides of the inequality


When is the only time you flip an inequality sign?

When you divide both sides of an inequality by a negative number, the inequality sign flips.


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 &gt; and &lt; 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.


Does an inequality change when you multiply by a negative?

Yes you have to flip the sign.


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

negative flip


Why do you flip the inequality sign when you multiply or divide by negative numbers?

because if you didn't the inequality would not be true. ex. -3x&lt;15 when you solve it WITHOUT CHANGING THE SIGN, you get x&lt;-5 when you graph that, a possible answer is -7 If you plug that in to the inequality, you get -3(-7)&lt;15 BUT that's not true! so therefor you need to flip the sign direction :)


Why must you flip the inequality symbol when?

I suspect you mean the signs &lt; and &gt; meaning "less than" or "greater than". (There is no flip of the inequality sign, which is an equals sign with a line through it). You have to flip when you multiply a "greater or less than" eqequation if you multiply the equatiob through by -1. Example: you have 2&gt;1, and -2&lt;-1.


Do you flip the sign of this inequality 8x plus 4y12?

Only when you multiply or divide by a negative number


Do you flip the inequality when adding and subtracting?

No. Only flip the inequality when multiplying or dividing by a negative number.


How do you solve the inequality?

you cant with the information that you gave


What must you do when solving an inequality with a negative coefficient?

Divide by negative one and flip the sign eg -x &gt; 6 / -1 /-1 x &lt; - 6


What do you do when you have a negative variable?

When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as &lt;, you would flip the sign to &gt; and vice versa.
