Math Problem Statement
Select the values that make the inequality 9d > 9 true. Then write an equivalent inequality, in terms of d.
Solution
The inequality provided is:
To solve this inequality, we divide both sides by 9:
This means that the values of that make the inequality true are those greater than 1. From the given options in the image, the correct values are:
The equivalent inequality is:
Would you like a more detailed explanation or further help?
Here are five questions to deepen your understanding:
- What is the process for solving inequalities involving multiplication or division?
- How would the inequality change if it were instead?
- Can you explain why values less than or equal to 1 do not satisfy the inequality?
- How would the solution change if the inequality sign was reversed, making it ?
- How can you graph the solution on a number line?
Tip: Always remember that when dividing or multiplying both sides of an inequality by a negative number, the inequality sign must be flipped!
