Math Problem Statement

–4|y|+2≤–10

Solution

To solve the inequality 4y+210-4|y| + 2 \leq -10, let's proceed step by step:

Step 1: Subtract 2 from both sides

4y12-4|y| \leq -12

Step 2: Divide both sides by 4-4

Since we're dividing by a negative number, we must reverse the inequality: y3|y| \geq 3

Step 3: Solve the absolute value inequality

The absolute value inequality y3|y| \geq 3 means that yy can be either greater than or equal to 3 or less than or equal to 3-3: y3ory3y \geq 3 \quad \text{or} \quad y \leq -3

Final Answer:

The solution to the inequality is: y3ory3y \geq 3 \quad \text{or} \quad y \leq -3
