How do you write a compound inequality?
A compound inequality is a sentence with two inequality statements joined either by the word “or” or by the word “and.” “And” indicates that both statements of the compound sentence are true at the same time. It is the overlap or intersection of the solution sets for the individual statements.
What does or mean in a compound inequality?
Feb 03, 2022 · A compound inequality is a combination of two or more inequalities joined by either an 'and' or an 'or.' In mathematics, most often we deal with equalities - two statements that must, at all times,...
How do you solve an and compound inequality?
A compound inequality is an inequality that combines two simple inequalities. Let's take a look at some examples. Example with "OR" So, for example, the numbers and are both solutions of the compound inequality, but the number is not a solution. Example with "AND"
What are the rules for solving compound inequalities?
A compound inequality is a statement of two inequality statements linked together either by the word or or by the word and. Sometimes, an and compound inequality is shown symbolically, like a < x < b, and does not even need the word and.Because compound inequalities represent either a union or intersection of the individual inequalities, graphing them on a number line can be a …
What is a compound inequality examples?
Compound inequalities are the derived form of inequalities, which are very useful in mathematics whenever dealing with a range of possible values. For example, after solving a particular linear inequality, you get two solutions, x > 3 and x < 12. You can read it as “3 is less than x, which is less than 12.
What are compound inequalities?
A compound inequality is an inequality that combines two simple inequalities. This article provides a review of how to graph and solve compound inequalities.
How do I write a compound inequality?

The way you do this is you write them separate.MoreThis is an example of an or compound inequality. The way you do this is you write them separate. Your x. Here would be less than or equal to because the arrow is going to the left.
What is a compound inequality and how is it solved?
A compound inequality is made up of two inequalities connected by the word “and” or the word “or.” To solve a compound inequality means to find all values of the variable that make the compound inequality a true statement. We solve compound inequalities using the same techniques we used to solve linear inequalities.13 Feb 2022
How do you tell if a compound inequality is and or OR?
A compound inequality contains at least two inequalities that are separated by either "and" or "or". The graph of a compound inequality with an "and" represents the intersection of the graph of the inequalities. A number is a solution to the compound inequality if the number is a solution to both inequalities.
What is a compound inequality in which the two simple inequalities are separated by the word or?
disjunction. a compound inequality in which the two simple inequalities are separated by the word "OR" intersection of two sets. the set of elements that could be found in both sets at the same time. union of two sets.
How do you read a compound inequality from a graph?
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 ...
How do you solve compound inequalities with fractions?
0:172:56Solving Compound Inequalities with fractions - YouTubeYouTubeStart of suggested clipEnd of suggested clipAnd we can do that by adding minus 5 to the 3 terms of this inequality. So minus 5 minus 5 minus 5MoreAnd we can do that by adding minus 5 to the 3 terms of this inequality. So minus 5 minus 5 minus 5 that will give us minus 2 minus 5 which is -7. Less than or equal to 5 minus 5 is 0.
What is a compound inequality in compact form?
Intersections When an inequality is combined by the word “and” the compound inequality is formed. However, usually the inequality is written in compact form indicating it is a compound inequality. Ex3) -2 ≤ 3x – 8 ≤ 10.
Example with "OR"
So, for example, the numbers and are both solutions of the compound inequality, but the number is not a solution.
Example with "AND"
This compound inequality is true for values that are both greater than zero and less than four. Graphically, we represent it like this:
What is the solution to a compound inequality?
There are three possible outcomes for compound inequalities joined by the word and: 1. The solution could be all the values between two endpoints. 2.
What is borderline high blood pressure?
Many times, solutions lie between two quantities, rather than continuing endlessly in one direction. For example systolic (top number) blood pressure that is between 120 and 139 mm Hg is called borderline high blood pressure. This can be described using a compound inequality, b < 139 and b > 120. Other compound inequalities are joined by the word “or”.
What is compound inequality?
A compound inequality consists of two inequalities that are joined together by the word "and" or the word "or".
What is the nice thing about "or" inequalities?
The nice thing about "Or" inequalities is that you will always see the word "or" in the problem. This makes it easier to distinguish between the two types of inequalities.
What is a disjunction in math?
A compound inequality that involves the word "OR " is called a disjunction. Hopefully by now you better understand the difference in the two types of compound inequalities and you have an idea of what the graph will look like for each type of compound inequality.
