Пошаговое объяснение:

║3x-7║-22=║3×(-0.5)-7║-22=║-1.5-7║-22=║-8.5║-22=8.5-22= -13.5

Answer 2

To evaluate the expression |3x - 7| - 22 at x = -0.5, we substitute -0.5 into the expression and simplify.

First, let's substitute x = -0.5 into the absolute value expression:

|3x - 7| = |3(-0.5) - 7| = |-1.5 - 7| = |-8.5| = 8.5

Now, we substitute the value of |3x - 7| into the original expression:

|3x - 7| - 22 = 8.5 - 22 = -13.5

Therefore, when x = -0.5, the value of the expression |3x - 7| - 22 is -13.5.
