Question

What is the solution for the inequality -10x ≤ 40?

a) x ≤ -4
b) x ≤ 4
c) x ≥ -4
d) x ≥ 4

Answer 1

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.
