Which graph represents the solution to the inequality shown?

A.
The number line shows numbers from -3 to 1. There is a closed circle at -3, a bold line from -3 heading rightwards.

B.
The number line shows numbers from -3 to 1. There is a closed circle at -3, a bold line from -3 heading leftwards.

C.
The number line shows numbers from -3 to 1. There is a open circle at -3, a bold line from -3 heading leftwards.

D.
The number line shows numbers from -3 to 1. There is a open circle at -3, a bold line from -3 heading rightwards.

Answer 1

First, we need to solve the inequality \( 5 \geq 2n + 11 \).

1. Subtract 11 from both sides: \[ 5 - 11 \geq 2n \] \[ -6 \geq 2n \]

2. Divide both sides by 2: \[ -3 \geq n \] or equivalently, \[ n \leq -3 \]

This means the solution to the inequality includes all numbers less than or equal to -3.

Now, looking at the graph options:

• A. A closed circle at -3 and a solid line heading right (indicates \( n \geq -3 \)) — not correct.

• B. A closed circle at -3 and a solid line heading left (indicates \( n \leq -3 \)) — correct.

• C. An open circle at -3 and a solid line heading left (indicates \( n < -3 \)) — not correct.

• D. An open circle at -3 and a solid line heading right (indicates \( n > -3 \)) — not correct.

The correct answer is: B. The number line shows numbers from -3 to 1. There is a closed circle at -3, a bold line from -3 heading leftwards.
