Question

Write a compound inequality that represents the following scenario: Supervision: Anyone under the age of 4 or under the age of ten, must be accompanied by an adult when in the store.

Answer 1

The compound inequality for the scenario is 0 ≤ x < 10, indicating that anyone who is at least 0 and less than 10 years old must be supervised by an adult in the store.

Step-by-step explanation:

To write a compound inequality that represents the scenario where anyone under the age of 4 or under the age of ten must be accompanied by an adult when in the store, we can set up two inequalities and combine them using the word 'or', since the rule applies to either age group. The compound inequality would be:

• 0 ≤ x < 4
• 0 ≤ x < 10

Here, 'x' represents the age of the person. However, since the age '4' is included in 'under the age of ten', we actually do not need the first inequality, so the correct compound inequality is simply:

0 ≤ x < 10

This means that if a person is at least 0 and less than 10 years old, they must be accompanied by an adult.
