Question

5x−3|y−8| при x=−7, y=−4.

Answer 1

$5x-|y-8|=5\cdot(-7)-3\cdot|-4-8|=-35-3\cdot|-12|=-35-3\cdot12=\\\\-35-36=-71$

Answer 2

To evaluate the expression 5x - 3|y - 8| at the given values x = -7 and y = -4, follow these steps:

1. Substitute the values of x and y into the expression: 5x - 3|y - 8| = 5(-7) - 3|-4 - 8|

2. Perform the calculations: = -35 - 3|-12| = -35 - 3 * 12 = -35 - 36 = -71

So, when x = -7 and y = -4, the value of the expression 5x - 3|y - 8| is -71.
