Question

Evaluate |–x – 2y| for x = –5 and y = 5. –15 15 5 –5

Answer 1

this is an absolute value problem.

Subst. -5 for x and 5 for y: |-(-5) - 2(5)| = |5 - 10| = |-5| = 5 (answer)

Answer 2

|-x - 2y|

x = -5
y = 5

|-(-5) - 2(5)|
| 5 - 10|
|-5|
Since this is a absolute value, it can only be positive

|-5| = 5

5 is your answer

hope this helps
