Question

Solve the inequality and graph the solution.
2+4j<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: 2 + 4j < 10
4j < 8
j < 2

Solution: j < 2, i.e. the interval (-∞, 2).

Graph: draw an open circle at 2 (since 2 is not included) and a ray/arrow extending left from 2 to indicate all numbers less than 2.
