Question

Solve the inequality and graph the solution.
5d–6≥4
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:
5d − 6 ≥ 4
Add 6 to both sides: 5d ≥ 10
Divide by 5: d ≥ 2

Solution: d ≥ 2 (interval notation: [2, ∞) ).

Graph: on the number line place a closed (solid) endpoint at 2 and draw a ray pointing to the right from 2 (arrow to the right).
