Question

Which inequality is represented by this graph?
A number line shows the numbers zero to ten. There is an open dot at six, and an arrow extending from that open dot toward the left.

two x is greater than or equal to twelve

x divided by two is less than six

three x is less than eighteen

x divided by 1 is less than or equal to six

Answer 1

quick lesson..
If there is an equal sign, there is a closed circle
If there is no equal sign, there is an open circle
(<) if it is less then, shading goes to the left
(>) if it is greater then, shading goes to the right

open dot at 6 means there is no equal sign.
arrow going towards the left means it is less then 6.
3x < 18
x < 6 -- answer C
