Answer:
<em>t ≥ -12 </em>
Step-by-step explanation:
4 ≥ -t/3 Original Equation
4 <em>(3</em>) ≥ -t/3 <em>(3) </em>Cancel out the division
12 ≥ -t
12 <em>(-1)</em> ≥ -t<em> (-1) </em>Canceling Negative on the variable, Flipping over Inequality Sign
<em>t ≥ -12 </em>

The roots of an equation are simply the x-intercepts of the equation.
See below for the proof that 
has at least two real roots
The equation is given as:
There are several ways to show that an equation has real roots, one of these ways is by using graphs.
See attachment for the graph of
Next, we count the x-intercepts of the graph (i.e. the points where the equation crosses the x-axis)
From the attached graph, we can see that crosses the x-axis at approximately <em>-2000 and 2000 </em>between the domain -2500 and 2500
This means that has at least two real roots
