\(ex. a\)

\(3x \ge 4\)

\(x \ge \dfrac{4}{3}\)

\(\dfrac{4}{3} = 1.3\)

\([1.3, \infty)\)
The interval has a bracket, not a parentheses, on the left to show an interval going right from 1.3 to infinity and including 1.3
:!: Not Shown on Post

The arrow representing the interval is going right, to infinity, from 1.3 with a solid circle at 1.3, due to 1.3 being in the interval.

\(ex. b\)

\(-5x \ge 15\)

\(x \le -\dfrac{15}{3}\)

\(x \le -3\)

\((-\infty, 3]\)
