In this example, there is an inclusive inequalityAn inequality that includes the boundary point indicated by the “
or equal” part of the symbols ≤ and ≥ and a closed dot on the number line
., which means that the lower-bound 2 is included in the solution. … The parentheses indicate the boundary is not included.
What are the four types of inequalities?
- political inequality;
- differing life outcomes;
- inequality of opportunity;
- treatment and responsibility;
- shared equality of membership in the areas of nation, faith and family.
What are some examples of inequalities?

What are the types of inequality in math?
- ≤: “less than or equal to”
- <: “less than”
- ≠: “not equal to”
- >: “greater than”
- ≥: “greater than or equal to”
How do you know if a compound inequality is AND or OR?
When a compound inequality is written without the expressed word “and” or “or,” it is understood to automatically be
the word “
and.” Reading { x|–3 < x < 4} from the “ x” position, you say (reading to the left), “ x is greater than –3 and (reading to the right) x is less than 4.” The graph of the solution set is shown …
What are the 3 different types of inequality?
- Income Inequality. Income inequality is the extent to which income is distributed unevenly in a group of people. Income. …

and inequality between subgroups (as in racial inequality).
What are all the inequality symbols?
These inequality symbols are:
less than (<), greater than (>), less than or equal (≤), greater than or equal (≥) and the not equal symbol (≠)
. Inequalities are used to compare numbers and determine the range or ranges of values that satisfy the conditions of a given variable.
What are the rules of inequalities?
- Add the same number on both sides.
- From both sides, subtract the same number.
- By the same positive number, multiply both sides.
- By the same positive number, divide both sides.
- Multiply the same negative number on both sides and reverse the sign.
How do you describe inequalities?
An inequality is a mathematical statement that compares two expressions using the ideas of greater than or less than. … When you read an inequality, read it from left to right—just like reading text on a page. In algebra, inequalities are
used to describe large sets of solutions
.
How are inequalities used in real life?
Inequalities are arguably used more often in “real life” than equalities. Businesses use inequalities
to control inventory, plan production lines, produce pricing models
, and for shipping/warehousing goods and materials.
How do you solve an OR compound inequality?
To solve a compound inequality,
first separate it into two inequalities
. Determine whether the answer should be a union of sets (“or”) or an intersection of sets (“and”). Then, solve both inequalities and graph.
