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. ...

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.
