which is the greatest absolute value: -17, -13, 15, 19

of the numbers given, only 15 and 19 are absolute values.

If you mean which of the numbers has the greatest absolute value, the answer is the same.

review the definition of absolute value.

To determine the greatest absolute value among -17, -13, 15, and 19, we need to compare the absolute values of these numbers.

The absolute value of a number is its distance from zero on the number line. It is always a positive value or zero.

The absolute value of -17 is 17.
The absolute value of -13 is 13.
The absolute value of 15 is 15.
The absolute value of 19 is 19.

Therefore, the greatest absolute value among -17, -13, 15, and 19 is 19.

To find the greatest absolute value among the given numbers (-17, -13, 15, 19), we need to compare the absolute values of each number and determine which one is the largest.

The absolute value of a number is its distance from zero on the number line. It is always a non-negative value.

To determine the absolute value of a number, we disregard its sign (positive or negative). If the number is positive, its absolute value is equal to the number itself. If the number is negative, its absolute value is the opposite (or negation) of the number.

Let's calculate the absolute values of each number:
- The absolute value of -17 is 17.
- The absolute value of -13 is 13.
- The absolute value of 15 is 15.
- The absolute value of 19 is 19.

Now, we compare these absolute values to find the greatest one. From the list, the greatest absolute value is 19.

Therefore, among -17, -13, 15, and 19, the greatest absolute value is 19.
