The absolute value of 7 is positive 7 because the distance from zero to 7 on the number line is seven units.
The absolute value of -9 on the number line will be 9 units from zero.
Explanation:
- The absolute value of a real number is only the number irrespective of its sign.
- For example: The absolute value of '6 is '6' and the absolute value of '-8 ' is 8.
- The absolute value of a number can also be thought of as the distance from zero along the number line of a real number.
Given :
1) Four statements describing absolute value.
2) The absolute value of -9 on a number line.
To find:
1) The true statement.
2) The absolute value of -9 on the number line.
Solution:
1)
The absolute value of a number can also be thought of as the distance from zero along the number line of a real number.
|7|=7
The absolute value of '7' is 7.
This is because the distance from zero to 7 on the number line is seven units.
The statement B is true.
2)
The absolute value of -9:
|-9|=9
The absolute value of -9 on the number line will be 9 units from zero.
