Question

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

Explanation:

Step1: Analyze the left part of the graph

The left green line starts from the left and has an open circle at 515, so the inequality for this part is \( x < 515 \).

Step2: Analyze the right part of the graph

The right green line starts from an open circle at 520 and goes to the right, so the inequality for this part is \( x > 520 \).

Step3: Combine the two inequalities

Since the graph shows two separate regions, we use "or" to combine the inequalities \( x < 515 \) and \( x > 520 \).

Answer:

\( x < 515 \) or \( x > 520 \)
