Question

solve the inequality and graph the solution. 6u + 20 < 2 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.

Explanation:

Step1: Subtract 20 from both sides

$6u + 20 - 20 < 2 - 20$
$6u < -18$

Step2: Divide both sides by 6

$\frac{6u}{6} < \frac{-18}{6}$
$u < -3$

Step3: Graph the solution

On the number line, plot an open circle at $-3$ (since the inequality is strict, no equality), then draw an arrow pointing left from this open circle to represent all values less than $-3$.

Answer:

The solution to the inequality is $u < -3$. For the graph: place an open endpoint at $-3$ on the number line, and draw an arrow extending to the left from this point.
