Question

what compound inequality describes this graph? write a compound inequality like 1 < x < 3 or like x < 1 or x > 3.

Explanation:

Step1: Identify the open - end point

The open circle is at 520, which means the value 520 is not included. So the inequality is $x>520$.

Step2: Identify the closed - end point

The closed circle is at 522, which means the value 522 is included. So the inequality is $x\leq522$.

Step3: Combine the inequalities

Since the solution set is between the two points, we use the "and" conjunction. The compound inequality is $520 < x\leq522$.

Answer:

$520 < x\leq522$
