Final answer:
The value of -12|8-7x| when x = -2 is -264.
Step-by-step explanation:
The value of -12|8-7x| when x = -2 can be calculated by substituting the value of x into the expression and performing the necessary operations.
First, we substitute x = -2 into the expression: -12|8 - 7(-2)|.
Next, we simplify the expression inside the absolute value: -12|8 + 14|.
Finally, we perform the multiplication and addition/subtraction: -12|22| = -12(22) = -264.
