Final answer:
To evaluate the expression -5s - 6 for s = -3, substitute -3 into the expression. The result is 15 - 6 = 9, a whole number.
Step-by-step explanation:
To evaluate the expression -5s - 6 for s = -3, you substitute -3 for s in the expression:
-5(-3) - 6 = 15 - 6 = 9
The result is 9, which is a whole number. Remember that when you multiply a negative number by a negative number, the result is positive. In this case, -5 multiplied by -3 gives us 15, and then we subtract 6 to get the final answer.
