Question

Find |x| when x = 15 and x = -15.

O15=15 and |-15| = -15
O Both values are -15.
O Both values are 15.
O|15| = -15 and |-15| = 15

Answer 1

The absolute value of both 15 and -15 is 15.

Therefore, the correct answer is: option 'Both values are 15.

Step-by-step explanation:

To find the absolute value of a number, we ignore its sign and consider only its magnitude.

The absolute value of a number is always positive or zero.

So, when x = 15, |x| = 15 because the absolute value of 15 is 15.

Similarly, when x = -15, |x| = 15 because the absolute value of -15 is also 15.

Therefore, both values of x, 15 and -15, have the same absolute value of 15.
