Question

Solve the inequality and graph the solution.
4j–6≥10
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:
4j − 6 ≥ 10
Add 6 to both sides: 4j ≥ 16
Divide by 4: j ≥ 4

Solution set: { j | j ≥ 4 } or in interval notation: [4, ∞)

Graph: on a number line place a closed (filled) dot at 4 and draw a ray/arrow extending to the right from 4. (Closed endpoint because the inequality is ≥.)
