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.
When you multiply both sides of any inequality by a negative number you need to do what to the inequality symbol?
You need to change it to the opposite direction; e.g 5 > 1; multiply both sides by -2 it becomes -10 < -2
When graphing a linear inequality the first step is to replace the inequality symbol with what sign?
With the equal sign (=).
Explain how solving inequalities is alike and different from solving equations?
Most of the steps are the same. The main difference is that if you multiply or divide both sides of an inequality by a NEGATIVE number, you must change the direction of the inequality sign (for example, change "less than" to "greater than").
What is A mathematical sentence which contains an inequality symbol and one variable raised to the first power is called a?
It is a linear inequality.

How do you divide by a negative in an inequality?
You divide as normal BUT you change the direction of the inequality symbol, so that < becomes > and conversely.
When solving an inequality when is it necessary to change the direction of the inequality symbol?
When the two sides of the inequality are multiplied or divided by a negative number or term or expression.
What is the effect of multiplying both sides of an inequality by a negative number?
It changes the direction of the inequality.
How do you know when to reverse the direction of an inequality symbol?
u only reverse the sign when u multiply or divide by a NEGATIVE number...otherwise u don't change the direction
When you multiply both sides of any inequality by a negative number you need to do what to the inequality symbol?
You need to change it to the opposite direction; e.g 5 > 1; multiply both sides by -2 it becomes -10 < -2
Is it true When dividing by a negative number the direction of the inequality symbol MUST be reversed?
Yes, it is true.
How do you put greater than symbol on the calculator?
Unless it's a fancy graphing calculator, you don't. When solving an inequality, you need to solve it as an equality, remaining mindful of the proper direction of the inequality symbol after each step.
When you divide both sides of an inequality by a positive value you must change the direction of the inequality sign?
No. Only when you divide by a negative.
If you multiply or divide both sides of an inquality by a negative number you need to?
Change the direction of the inequality.
When subtracting a number from both sides of an inequality?
The inequality is maintained with the direction of the inequality unchanged.
What is the comparison symbol of 4 1?
The inequality symbol.
