Question

Which number line represents the solution set for the inequality 3x < –9? A number line from negative 4 to 4 in increments of 1. A point is at negative 3 and a bold line starts at negative 3 and is pointing to the left. A number line from negative 4 to 4 in increments of 1. A point is at negative 3 and a bold line starts at negative 3 and is pointing to the right. A number line from negative 4 to 4 in increments of 1. An open circle is at negative 3 and a bold line starts at negative 3 and is pointing to the left. A number line from negative 4 to 4 in increments of 1. An open circle is at negative 3 and a bold line starts at negative 3 and is pointing to the right.

Answer 1

its C

E 2 0 2 0

unfortunately i cant explain

Answer 2

An open circle is at negative 3 and a bold line starts at negative 3 and is pointing to the left will represent the inequality on a number line.

Explanation:

`3x< -9`

therefore
`x< (-9)/(3)`

`x< -3`

therefor the line segment does not include -3

if we have a point in -3 it means that -3 is included

and if we have a open circle in -3 it means that -3 is not included.

therefore a line segment with an open circle at -3 and a bold line to the left of -3 will denote the inequality.
