Answer:
In choice A, the compound inequality x ≤ 6 OR x > 9 and the graph match the given simple inequalities
Explanation:
In the compound inequality
- If the sign of inequality is >, then the arrow represented it pointed to the right
- If the sign of inequality is <, then the arrow represented it pointed to the left
- If the sign of inequality is ≥ or ≤, then the end of the arrow is a bold circle
- If the sign of inequality is > or <, then the end of the arrow is an empty circle
Let us solve the question
∵ x ≤ 6
∴ The arrow represents it is starting at 6 with a bold circle and
pointed to the left side
∵ x > 9
∴ The arrow represents it is starting at 9 with an empty circle and
pointed to the right side
→ Look at the graphs to find the answer that represents the information
above
In choice A
∵ an arrow with a bold end started from 6 and pointed to the left
∵ an arrow with an empty end started from 9 and pointed to the right
∴ x ≤ 6 OR x > 9 and the graph match the given simple inequalities
