Absolute Inequality
1. State the problem: Solve the inequality $$|8d| - 2 \geq 14$$ for $$d$$ and write the answer as a compound inequality.
2. Isolate the absolute value expression:
$$|8d| - 2 \geq 14$$
Add 2 to both sides:
$$|8d| \geq 16$$
3. Write the corresponding compound inequality for $$|8d| \geq 16$$:
This means that either
$$8d \geq 16$$ or $$8d \leq -16$$
4. Solve each inequality for $$d$$:
From $$8d \geq 16$$,
Divide both sides by 8:
$$d \geq 2$$
From $$8d \leq -16$$,
Divide both sides by 8:
$$d \leq -2$$
5. Write the final compound inequality:
$$d \leq -2 \quad \text{or} \quad d \geq 2$$
This means the solution set is all $$d$$ less than or equal to $$-2$$ or greater than or equal to $$2$$.
