Answer:

x < -3

Step-by-step explanation:

1. To put this inequality on a number line, we first must solve it.

Step 1: Subtract 15 from both sides.

  • [tex]5x + 15 - 15 < 0 - 15[/tex]
  • [tex]5x < -15[/tex]  

Step 2: Divide both sides by 5.

  • [tex]\frac{5x}{5} <\frac{-15}{5}[/tex]
  • [tex]x < -3[/tex]

2. Now that we know x < -3, let's graph it!

  • Since it's less than, we make the number line point to the left, and we make the circle open.
