Answer 2

To evaluate the expression 2x – 7 |y – 9| when x = -9 and y = -8, we substitute these values into the expression:

2x – 7 |y – 9|

Substitute x = -9 and y = -8:

2(-9) – 7 |(-8) – 9| -18 - 7 |-8 - 9| -18 - 7 |-17| -18 - 119 -137

So, when x = -9 and y = -8, the value of the expression 2x – 7 |y – 9| is -137.
