1. State the problem: Express each statement using an inequality involving absolute value. 2. Use the absolute value modeling rule: - “within $k$ units of $a$” means $|x-a| \le k$. 3. Statement 1 (plant height): - Standard size is 13 inches. - “Within 2 inches” means the height is at most 2 away from 13. 4. Write the absolute value inequality: $$|h-13| \le 2$$ 5. Interpret the inequality in words: - The height $h$ can be any value from $13-2$ to $13+2$ (inclusive). 6. Find the range (optional check): - $13-2=11$ - $13+2=15$ So $11 \le h \le 15$. 7. Final answer: $$|h-13| \le 2$$
