Math Problem Statement

Solve the inequality problem: -6(y - 3) ≤ 36 or 12 + y < 15. Express your answer in interval notation.

Solution

The image contains an inequality problem with two parts:

  1. 6(y3)36-6(y - 3) \leq 36
  2. 12+y<1512 + y < 15

We need to solve these inequalities and express the solution in interval notation.

Step 1: Solve the first inequality:

6(y3)36-6(y - 3) \leq 36 Distribute the 6-6: 6y+1836-6y + 18 \leq 36 Subtract 18 from both sides: 6y18-6y \leq 18 Divide by 6-6 (and reverse the inequality because of dividing by a negative number): y3y \geq -3

Step 2: Solve the second inequality:

12+y<1512 + y < 15 Subtract 12 from both sides: y<3y < 3

Step 3: Combine the solutions:

The first inequality gives y3y \geq -3 and the second gives y<3y < 3.

In interval notation, this is: [3,3)[-3, 3)

This is the final solution for the combined inequalities.
