what is the solution set for $4.8geq12k + 1.2$?\na $kleq0.3$\nb $kgeq3$\nc $kleq2$\nd $kgeq0.3$
Answer
Explanation:
Step1: Subtract 1.2 from both sides
$$4.8 - 1.2\geq12k+1.2 - 1.2$$ $$3.6\geq12k$$
Step2: Divide both sides by 12
$$\frac{3.6}{12}\geq\frac{12k}{12}$$ $$0.3\geq k$$
Answer:
A. (k\leq0.3)
