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.
What happens to the inequality sign when you divide by a negative integer?
When you divide or multiply both sides of an inequality by a negative integer, the inequality sign must be reversed. For example, if you have the inequality (a < b) and you divide both sides by a negative number, the resulting inequality will be (a / (-n) > b / (-n)), where (n) is a positive integer. This reversal is necessary to maintain the truth of the inequality.
When you multiply both sides of an inequality by a number that is?
When you multiply both sides of an inequality by a positive number, the direction of the inequality remains unchanged. However, if you multiply both sides by a negative number, the direction of the inequality must be reversed. This is crucial to maintain the truth of the inequality. Always be mindful of the sign of the number you are multiplying by.
When should the inequality sign be flipped?
when you divide the inequality by a negative number, for example -2x > 50 then x < -25

When you multiply both sides of any inequality by a negative number you need to the inequality symbol?
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.
When should the inequality sign be flipped?
when you divide the inequality by a negative number, for example -2x > 50 then x < -25
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 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.

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.
