Question

or
Solve the inequality and graph the solution.
9+9k>
–
9
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: 9 + 9k > −9

1. Subtract 9 from both sides: 9k > −18
2. Divide by 9: k > −2

Solution: k > −2 (interval notation: (−2, ∞)).

Graph: open circle at −2 with a ray/arrow pointing to the right (values greater than −2).
