According to the site Math Planet, 'A compound inequality contains at least two inequalities that are separated by either "and" or "or".'

In the case of "and", a compound inequality such as

x > -1 and x < 2

can also be written as:

-1 < x < 2

(I also took this example from Math Planet.)

There is no such shortcut for the "or" case.

Compound inequality definition?

A compound inequality is a mathematical statement that combines two or more inequalities, typically connected by the words &quot;and&quot; or &quot;or.&quot; For example, an &quot;and&quot; compound inequality requires that both inequalities be true simultaneously, while an &quot;or&quot; compound inequality allows for either inequality to be true. These inequalities can be used to define a range of values that satisfy the conditions set by the inequalities. Compound inequalities are often solved by isolating the variable involved, similar to solving single inequalities.


Is an inequality the same thing as a compound inequality?

A compound inequality would be a combination of two or more inequalities, combined with AND or with OR. This can be implied, as in 2 &lt; x &lt; 5, which means: 2 &lt; x AND x &lt; 5.

What is the difference between a compound inequality using the word and and compound inequality using the word or?

The difference between them is that when solving an "and" inequality you are comparing two inequalities and when you are solving an "or" inequality you dont compare, you only use one inequality example of "and" . 2&lt;x+3&lt;7 example of "or" . 4&lt;d or m&lt;1


How can you tell what kind of compound inequality an absolute value inequality will represent?

If the absolute value inequality is of the form where the absolute value of the difference between a variable (X) and some constant (a) is compared to another constant (b) eg |X - a| compared with b, then if the comparison is &lt; or &acirc;&permil;&curren;, the compound inequality is a double inequality of the form c &lt; X &lt; d (or &acirc;&permil;&curren;), and if the comparison is &gt; or &acirc;&permil;&yen;, the compound inequality is a disjoint inequality of the form X &lt; c or X &gt; d (or including the equals). In both cases, c = b - a, d = b + a (&gt;c)

What is the name for two inequalities written as one inequality?

The name for two inequalities written as one inequality is a &quot;compound inequality.&quot; This format expresses relationships involving two conditions simultaneously, often using &quot;and&quot; or &quot;or&quot; to connect them. For example, the compound inequality (3 &lt; x &lt; 7) combines two inequalities, (3 &lt; x) and (x &lt; 7).
