Translate the sentence into an inequality.

Four subtracted from c is at least -26.

To translate the sentence "Four subtracted from c is at least -26" into an inequality, we first identify the terms:

- "Four subtracted from c" means \( c - 4 \)
- "Is at least" means the expression on the left side must be greater than or equal to the expression on the right side.
- "-26" is the value that \( c - 4 \) must be at least as great as.

Therefore, the inequality that represents the sentence is:

\( c - 4 \geq -26 \)
