Final answer:
To solve the inequality -10x ≤ 40, divide both sides by -10 and reverse the inequality sign, which gives x ≥ -4. The correct answer is c) x ≥ -4.
Step-by-step explanation:
The student has asked for the solution to the inequality -10x ≤ 40. To solve this inequality, we can divide both sides by -10, remembering to reverse the inequality sign because we are dividing by a negative number. This gives us:
x ≥ -4
Therefore, the correct answer is c) x ≥ -4.
