To solve the inequality \(-4 \leq \frac{t}{7}\), follow these steps:
1. **Multiply both sides by 7**: Since 7 is positive, the direction of the inequality remains the same.
\[
-4 \times 7 \leq \frac{t}{7} \times 7
\]
This simplifies to:
\[
-28 \leq t
\]
2. **Rearranging the inequality**: The result can also be written as:
\[
t \geq -28
\]
So, the solution to the inequality is:
\[
t \geq -28
\]
This means that \(t\) can take any value greater than or equal to \(-28\).
