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.

Answer 1

Answer:

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.

Step-by-step explanation:

$3x< -9$

therefore $x< \frac{-9}{3}$

$x< -3$

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.

Answer 2

its C

E 2 0 2 0

unfortunately i cant explain
