Answer:

Explanation:

Multiply both sides by 5(k - 2)

-8*5(k - 2) ≤2 Combine -8 and 5

-40 (k - 2) ≤2 Remove the brackets

-40k + 80 ≤2 Subtract 80 from both sides

-40k ≤ -78 Here's the trick part. Pay attention. Divide by - 40

k ≥ - 78 /- 40

k ≥ 1.95

Did you see what happened? The ≤ operation turned into ≥ That always happens when dividing by a minus or multiplying by a minus or if you change the side where literal coefficient is.
