Step 1: Define

Identify

-10x ≤ 40

Step 2: Solve for x

  1. [Division Property of Equality] Divide -10 on both sides:                               x ≥ -4

Answer:

C. x ≥ -4

Step-by-step explanation:

To solve this inequality isolate the variable. Do this by using the properties of equality, specifically the division property. So, divide both sides by -10. This equals, x ≤ -4. However, whenever an inequality is divided or multiplied by a negative number the sign must be flipped. Therefore, the final answer is x ≥ -4.
