solve it you get x>-2
and 3x<=15
x<=5
so close on 5 open on -2
so C

C) A number line with an open circle on −2, a closed circle on 5, and shading in between

Remember that the symbols: < and > (read "less than" and "greater than" respectively) translates into an open circle in the number line.

The symbols: ≤ and ≥ (read "less or equal than" and "Greater or equal than" respectively) translates into a closed circle in the number line.

Now, let's solve each inequality:

[tex]x-2>-4[/tex]

[tex]x>-2[/tex] So we have an open circle on -2

3x less than or equal to 15

[tex]3x\leq 15[/tex]

[tex]x\leq \frac{15}{3}[/tex]

[tex]x\leq 5[/tex] So we have a closed circle on 5

Our inequalities goes from -2 (open circle) to 5 (closed circle) on the number line.
