Math Problem Statement

Solve and graph the inequality: 22 ≥ 5(2y + 3) - 3y.

Solution

Let's solve the given inequality step by step.

The inequality is:

225(2y+3)3y22 \geq 5(2y + 3) - 3y

Step 1: Expand the expression on the right-hand side.

Distribute the 55 over the terms inside the parentheses:

5(2y+3)=10y+155(2y + 3) = 10y + 15

So, the inequality becomes:

2210y+153y22 \geq 10y + 15 - 3y

Step 2: Combine like terms.

Now, combine the terms involving yy:

10y3y=7y10y - 3y = 7y

This simplifies the inequality to:

227y+1522 \geq 7y + 15

Step 3: Solve for yy.

First, subtract 15 from both sides:

22157y22 - 15 \geq 7y 77y7 \geq 7y

Next, divide both sides by 7:

1y1 \geq y

or equivalently:

y1y \leq 1

Step 4: Graph the inequality.

The solution is y1y \leq 1, which means all values of yy less than or equal to 1. On a number line, this would be represented by a closed circle at 11 with an arrow extending to the left (since yy is less than or equal to 1).

Final Answer:

  • The correct answer for the inequality is y1y \leq 1.
  • The graph should show a closed circle at 11 and a line extending to the left, covering values less than or equal to 1.

Here are five follow-up questions based on this:

  1. How do you solve inequalities with multiple steps?
  2. What happens if you multiply or divide an inequality by a negative number?
  3. How would the solution change if the inequality symbol was reversed?
  4. How can you check if a given value is a solution to an inequality?
  5. What is the difference between solving an equation and solving an inequality?

Tip: When graphing inequalities, always pay attention to whether the inequality is strict (< or >) or inclusive (≤ or ≥) for determining open or closed circles on the graph.
