Question

Solve the inequality and graph the solution.
3j+9<3
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:
3j + 9 < 3
Subtract 9: 3j < 3 − 9 = −6
Divide by 3: j < −2

Interval notation: (−∞, −2)

Graph: open circle at −2 with a ray pointing left (since values less than −2).
ASCII sketch:
... −4 −3 −2 −1 0
o←←←←←

(Select the endpoint at −2 and make it open, then place the arrow pointing left.)
