Question

use the number line to represent the solution to $2.4x - 6 > - 13.2$. select the correct ray, then click the location on the number line for the endpoint of the ray.

Explanation:

Step1: Add 6 to both sides

$$2.4x-6 + 6> - 13.2+6$$
$$2.4x>-7.2$$

Step2: Divide both sides by 2.4

$$\frac{2.4x}{2.4}>\frac{-7.2}{2.4}$$
$$x > - 3$$

Since \(x>-3\), on the number - line, we use an open circle at \(x = - 3\) (because the inequality is strict, \(x
eq - 3\)) and draw a ray to the right.

Answer:

We select the ray with an open circle (the second option in the ray - selection box, the one that is \( \circ
ightarrow\)) and place the open - circle at \(x=-3\) on the number line.
