Question

Evaluate the expression when x = 9:

5∣∣6−x∣∣

Answer 1

15

Explanation:

Change x to the declared value:
`5|6-9|`

Subtract:
`5|6-9| = 5|-3|`

NOTE: remember that little minus big = negative of big minus little.

i.e.: 6-9 = -(9-6) = -(3) = -3

Evaluate the Absolute Value:
`5|-3| = 5(3)`

NOTE: remember that the absolute value of a number = the number's distance from 0 (always a positive number).

i.e.: |-2| = 2; |5| = 5

Multiply:
`5(3) = 15`
