Question

solve the inequality and graph the solution.
$k \geq 1 + 8$
to draw a ray, plot an endpoint and select an arrow. select an endpoint to change it from closed to open. select the middle of the ray to delete it.
0 1 2 3 4 5 6 7 8 9 10

Explanation:

Step1: Simplify the right side

Calculate \(1 + 8\), which equals \(9\). So the inequality becomes \(k\geq9\).

Step2: Graph the solution

On the number line, we plot a closed endpoint at \(9\) (because the inequality is "greater than or equal to") and draw an arrow to the right to represent all numbers greater than or equal to \(9\).

Answer:

The solution to the inequality \(k\geq1 + 8\) is \(k\geq9\). For the graph, there is a closed dot at \(9\) and an arrow pointing to the right.
