Answer 2

Finding the Value of the Expression 9x−5|y−8| at x=−3, y=−2

To find the value of the expression 9x−5|y−8| when x=−3 and y=−2, we can substitute these values into the expression and perform the necessary calculations.

Substituting x=−3 and y=−2 into the expression 9x−5|y−8|: 9*(-3) - 5*|-2-8|

Now, let's calculate the value of the expression step by step.

First, calculate the absolute value of (y−8): |-2-8| = |-10| = 10

Now, substitute this absolute value into the expression: 9*(-3) - 5*10 = -27 - 50 = -77

So, the value of the expression 9x−5|y−8| at x=−3, y=−2 is -77.

This calculation is based on the mathematical principles of substitution and the order of operations.
