Answer 2

To evaluate the expression 5x - 4|y - 6| - 9 when x = -3 and y = -8, we need to substitute these values into the expression and perform the calculations step by step.

Step 1: Substitute the given values of x and y into the expression: 5(-3) - 4|(-8) - 6| - 9

Step 2: Perform the calculations inside the absolute value: 5(-3) - 4|(-8 - 6)| - 9 -15 - 4|-14| - 9

Step 3: Calculate the absolute value: -15 - 4 * 14 - 9

Step 4: Perform the multiplication and addition: -15 - 56 - 9

Step 5: Simplify the expression further: -80 - 9

Step 6: Finally, calculate the result: -89

So, when x = -3 and y = -8, the value of the expression 5x - 4|y - 6| - 9 is -89.
