Question #0bf4a

Answer 1

`t \in [-3,\infty)`.

Explanation:

Divide both terms by `-4`, keeping in mind that dividing both terms of an inequality by a negative number also means to invert the inequality symbol:

`-4t \le 12 -> t \ge -3`.

And this is basically it: we've expressed our inequality as an interval: all the number greater than or equal to `-3`, in interval notation

`t \in [-3,\infty)`.
