Question

Solve -4x - 5 > -9 and describe the graph of the solution.

x > 1; closed circle on 1, shading to the right

x < 1; closed circle on 1, shading to the left

x < 1; open circle on 1, shading to the left

x > 1; open circle on 1, shading to the right

Answer 1

Hints:

1. Add 4x and 9 to both sides
2. Isolate x
3. No line below the inequality implies "open circle".
