# What are compound inequalities?

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.

Let’s take a closer look at a compound inequality that uses or to combine two inequalities. For example, x > 6 or x < 2. The solution to this compound inequality is all the values of x in which x is either greater than 6 or x is less than 2. Everything else on the graph is a solution to this compound inequality.

Also, how do compound inequalities work? 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.

Considering this, 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.

What is the inequality?

An inequality says that two values are not equal. a ≠ b says that a is not equal to b. There are other special symbols that show in what way things are not equal. a < b says that a is less than b. a > b says that a is greater than b.

### What does a compound inequality look like?

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. “Or” indicates that, as long as either statement is true, the entire compound sentence is true.

### What is the definition of compound inequality?

A compound inequality is an equation with two or more inequalities joined together with either “and” or “or” (for example, and ; or ). When two inequalities are joined with and, they are often written simply as a double inequality, like: .

### What is the difference between and and/or in compound inequalities?

The key difference is with “or”, x only needs to satisfy one of the inequalities. With “and”, x needs to satisfy both. It turns out x=7 satisfies the compound inequality. This is because x satisfies the first inequality 7>6.

### Can you write a compound inequality that has no solution?

An intersection of 2 sets is where the sets overlap (or which values are in common). If you graph the 2 inequality solutions, you can see that they have no values in common. There is no overlap in their 2 sets. This is why the compound inequality has no solution.

### How do you solve the inequality?

To solve an inequality use the following steps: Step 1 Eliminate fractions by multiplying all terms by the least common denominator of all fractions. Step 2 Simplify by combining like terms on each side of the inequality. Step 3 Add or subtract quantities to obtain the unknown on one side and the numbers on the other.

### What is the solution to inequality?

A “solution” of an inequality is a number which when substituted for the variable makes the inequality a true statement. When we substitute 8 for x, the inequality becomes 8-2 > 5. Thus, x=8 is a solution of the inequality.

### What is linear inequality in math?

In mathematics a linear inequality is an inequality which involves a linear function. A linear inequality contains one of the symbols of inequality:. It shows the data which is not equal in graph form. < is less than.

### How do you know if an inequality is all real numbers?

If the inequality states something untrue there is no solution. If an inequality would be true for all possible values, the answer is all real numbers.

### Are absolute value inequalities AND or OR?

This pattern for “greater than” absolute-value inequalities always holds: Given the inequality | x | > a, the solution always starts by splitting the inequality into two pieces: x < –a or x > a. And, by the way, the correct conjunction is “or”, not “and”.
