Question

2. Graph each inequality on a number line: 5x + 15 < 0

Answer 1

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.

• $5x + 15 - 15 < 0 - 15$

• $5x < -15$  

Step 2: Divide both sides by 5.

• $\frac{5x}{5}$
• $x < -3$

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.
