Choose the graph which represents the solution to the inequality:<br> 3x + 8 ≥ 11
Mashutka [201]

The solution of the inequality is x ≥ 1.

Solution:

Given inequality:

3 x+8 \geq 11

To find the solution of the inequality:

3 x+8 \geq 11

Subtract 8 from both sides.

3 x+8-8 \geq 11-8

3 x \geq 3

Divide by 3 on both sides.

$\frac{3 x}{3} \geq \frac{3}{3}

On simplifying this, we get

x \geq 1

The solution of the inequality is x ≥ 1.

The graph of the solution is attached below.
