Question

7у+(-3)|х+8| при х=-2,у=-3

Answer 1

Вместо х и у подставляешь числа указанные на задании.

Answer 2

To evaluate the expression 7у + (-3)|х + 8| when х = -2 and у = -3, we substitute the given values into the expression and perform the necessary calculations.

First, let's substitute х = -2 and у = -3 into the expression:

7(-3) + (-3)|-2 + 8|

Next, we simplify the absolute value expression:

7(-3) + (-3)|-2 + 8| -21 + (-3)|-2 + 8|

Since the absolute value of -2 + 8 is positive, we can remove the absolute value signs:

-21 + (-3)(-2 + 8)

Simplifying further:

-21 + (-3)(6) -21 + (-18) -39

Therefore, when х = -2 and у = -3, the value of the expression 7у + (-3)|х + 8| is -39.
