The equation \( d \geq -15 \) represents a relationship rather than a specific operation being applied to change the inequality. However, if you were to consider the context in which you might manipulate this inequality (for example, if you wanted to isolate \( d \) by adding or subtracting a constant), then you could technically apply any of the properties of inequality, depending on your operations.
- Addition property of Inequality: Adding the same value to both sides of the inequality.
- Subtraction property of Inequality: Subtracting the same value from both sides of the inequality.
- Multiplication property of Inequality: Multiplying both sides of the inequality by a positive number (or appropriately in the case of negative).
- Division property of Inequality: Dividing both sides of the inequality by a positive number (or appropriately in the case of negative).
Since \( d \geq -15 \) is simply stating that \( d \) is greater than or equal to \(-15\), it doesn’t explicitly apply one of these properties. You would need to manipulate the inequality to demonstrate the use of one of the properties.
Therefore, no specific property is being demonstrated in the equation itself, but the relevant ones would be the Addition property of Inequality or Subtraction property of Inequality if you were to change or isolate \( d \).
If the intention is just to identify the property being applied to arrive at that form, you would typically describe the manipulation required in the context, citing the relevant property based on the operation performed.
