Flip the inequality sign **when you multiply or divide both sides of an inequality by a negative number**. You also often need to flip the inequality sign when solving inequalities with absolute values.

Afterall, why do you have to flip the inequality sign?

When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign **whenever you multiply by a negative number**.

Even, does inverting an inequality flip the sign? Additive Inverse As we just saw, putting minuses in front of a and b changes the direction of the inequality. This is called the "Additive Inverse": **If a < b then âˆ’a > âˆ’b**.

Other than that, what inequality symbol is at most?

The notation **a â‰¤ b or a â©½ b** means that a is less than or equal to b (or, equivalently, at most b, or not greater than b).

What are the four inequalities?

When we look at inequalities, we are looking at two expressions that are â€œinequalâ€ or unequal to each other, as the name suggests. This means that one equation will be larger than the other. The four basic inequalities are: **less than, greater than, less than or equal to, and greater than or equal to.**

A solution for an inequality in x is a number such that when we substitute that number for x we have a true statement. So, 4 is a solution for example 1, while 8 is not. The solution set of an inequality is **the set of all solutions**.

3/4 is the reciprocal of **4/3**. The reciprocal of 3 is 1/3.

(Figure 1) Hence squaring both sides of an inequality will be **valid as long as both sides are non-negative**. Since square roots are non-negative, inequality (2) is only meaningful if both sides are non-negative. ... Hence, squaring inequalities involving negative numbers will reverse the inequality.

To plot an inequality, such as x>3, on a number line, first draw a circle over the number (e.g., 3). Then if the sign includes equal to (â‰¥ or â‰¤), fill in the circle. ... Finally, draw a line going from the circle in the direction of the numbers that make the inequality true.

These inequality symbols are: **less than (<), greater than (>), less than or equal (â‰¤), greater than or equal (â‰¥)** and the not equal symbol (â‰ ).

> | Greater than or equal to |

< | Less than |

< | Less than or equal to |

The definition of inequality is a difference in size, amount, quality, social position or other factor. An example of inequality is **when you have ten of something and someone else has none**. (mathematics) A statement that of two quantities one is specifically less than (greater than) another.

Social scientists study two kinds of inequality: **inequality between persons (as in income inequality)** and inequality between subgroups (as in racial inequality).

A quadratic inequality is an **equation of second degree that uses an inequality sign** instead of an equal sign. Examples of quadratic inequalities are: x2 â€“ 6x â€“ 16 â‰¤ 0, 2x2 â€“ 11x + 12 > 0, x2 + 4 > 0, x2 â€“ 3x + 2 â‰¤ 0 etc. Solving a quadratic inequality in Algebra is similar to solving a quadratic equation.
