Question

Solve the inequality and graph the solution.
11–2j≤15
To draw a ray, plot an endpoint and select an arrow. Select an endpoint to change it from closed to open. Select the middle of the ray to delete it.

Answer 1

Solve:
11 − 2j ≤ 15
Subtract 11: −2j ≤ 4
Divide by −2 (reverse inequality): j ≥ −2

Interval notation: [−2, ∞)

Graph: closed dot at −2 with a ray/arrow pointing to the right (all numbers ≥ −2).
