When should an inequality sign be reversed?
When one side of the inequality is divided or multiplied by a negative number.
What happens to the inequality when it is multiplied by a negative number?
The inequality is "flipped" when multiplied by a negative number. For example, if x > y and a is a negative number, then ax < ay.
If you replace the equal sign of an equation an put an inequality sign in its place is there ever a time when the same value will be a solution to both the equation and inequality?
Yes, when the inequality has a less that or equal to sign, or a greater than sign or equal to sign, then the equal sign can be replaced and get a solution that is common to both the equation and the inequality. There can also be other solutions to the inequality, where as the solution for the equation will be a valid one.

What must occur in a linear inequality when you divide or multiply by a negative number?
The inequality sign must be flipped.
When do you flip the inequality sign?
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)
When should an inequality sign be reversed?

What is a solution to the inequality x281?
"x281" is an expression, not an inequality. An inequality is supposed to have an inequality sign, such as "<" or ">".
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.
What happens to the inequality when it is multiplied by a negative number?
The inequality is "flipped" when multiplied by a negative number. For example, if x > y and a is a negative number, then ax < ay.
What is the inequality of 13 X plus 2665?
There is no inequality since there is no inequality sign.
When graphing a linear inequality the first step is to replace the inequality symbol with what sign?
With the equal sign (=).
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 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.
