Answer: [-1, ∞)
Explanation:
First, we will simplify the equation.
Given:
t - 1/3 ≥ -12/9
Add 1/3 to both sides of the equation:
t ≥ -1
Next, we know that a bracket is used when representing greater than or equal to and less than or equal to. Here, it's greater than or equal to so we will use a bracket on the left side.
Then, t can be any value to infinity above -1, so we will use ∞) on the right side.
[-1, ∞)
