When solving an inequality, you must revers the inequality sign when you multiply (or divide) both sides by a negative number.
When you divide both sides by a negative value
"x281" is an expression, not an inequality. An inequality is supposed to have an inequality sign, such as "<" or ">".
u only reverse the sign when u multiply or divide by a NEGATIVE number...otherwise u don't change the direction
When you divide both sides of an inequality by a negative number, the inequality sign flips.
You solve an inequality in the same way as you would solve an equality (equation). The only difference is that if you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality sign. Thus, if you have -3x < 9 to find x, you need to divide by -3. That is a negative number so -3x/(-3) > 9/(-3) reverse inequality x > -3
When your teacher comes and your not sure what the answer is.
There is no inequality since there is no inequality sign.
With the equal sign (=).
No. An inequality must have an inequality sign, for example, "<".
This is not an inequality. There is no <,>, or = sign.
No, you only flip the inequality sign if you are dividing by a negative number on both sides of the 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.
When multiplying or dividing a negative number or variable.
The inequality sign opens towards the bigger number.
If the inequality has a > or ≥ sign, you shade above the line. If the inequality has a < or ≤ sign, you shade below it. Obviously, just an = is an equation, not an inequality.
An inequality must have a greater than sign (>) OR a less than sign (<) OR a greater than or equal to sign (≥) OR a less than or equal to sign (≤).
Leave it alone. You cannot make an inequality into an equality by multiplying both sides of the inequation by the same number. If instead of the inequality sign you are using a lesser or greater than sign, however, you will need to reverse it if you multiply both sides by the same negative number, e.g. 10>4. If you multiply both sides by -2, you need to change the > into a <, so -20<-8
A number is an expression. It is not an equation, or an inequality, since it doesn't have an equal sign, or an inequality (greater than, less than, etc.) sign.
It is the 'equals' sign with a diagonal slash through it.
