Question

2x + 8 > -4

x = 4

Describe how to graph it on a number line.

Answer 1

Explanation:

Focus on 2x + 8 > -4 first. Solve for x: Subtract 8 from both sides, which results in 2x > -12.

Dividing both sides by 2, we get x > -6.

Draw an open circle around -6 on the number line, and then draw an arrow to the right from x = -6.

Note that letting x = 4 is not helpful. 2(4) + 8 > -4 is true (16 > -4 is true).
