Question

Evaluate the expression when x =-4

Answer 1

22. 2 (-4) = -8

23. (2(-4) + 11) = (-8 + 11) = 3

24. -3 (5 (-4) = -3 (-20) = 60

Answer 2

22. 8

23. 3

24. -60

Explanation:

You want the values of the given absolute value expressions when x = -4.

23. 2|x|

The absolute value function changes the sign to positive, if it isn't already.

2|-4| = 2(4) = 8

24. |2x +11|

|2(-4) +11| = |-8 +11| = |3| = 3

25. -3|5x|

-3|5(-4)| = -3|-20| = -3(20) = -60
