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 < x < 5, which means: 2 < x AND x < 5.
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 < or ≤, the compound inequality is a double inequality of the form c < X < d (or ≤), and if the comparison is > or ≥, the compound inequality is a disjoint inequality of the form X < c or X > d (or including the equals). In both cases, c = b - a, d = b + a (>c)
What does and mean in a compound inequality?
It means that both inequalities must be satisfied.
How do you write x6 and x18 as a compound inequalities?
represent x > 6 and x <=18 enter the compound inequality without using and
Explain in your own words the difference between compound inequalities with and and those with or?
An inequality with "and" is true if BOTH inequalities are true. Inequality with "or" is true if ONE of the inequalities are true.
