Question

4у-3×|2-х| при х=-1, у=-8

Answer 1

Поставляем значения переменных в выражение
$4 \times ( - 8) - 3 |2 - ( - 1)| = - 32 - 3 |2 + 1| = - 32 - 3 \times |3| = - 32 - 3 \times 3 = - 32 - 9 = - 41$

Answer 2

To find the value of the expression 4у - 3×|2-х| when х = -1 and у = -8, substitute the given values into the expression:

4у - 3×|2-х| = 4(-8) - 3×|2-(-1)|

Now, simplify the expression inside the absolute value:

2 - (-1) = 2 + 1 = 3

Substitute this back into the expression:

4(-8) - 3×|3| = -32 - 3×3

Now, calculate the value inside the second set of absolute value:

|3| = 3

Substitute this back into the expression:

-32 - 3×3 = -32 - 9 = -41

So, when х = -1 and у = -8, the value of the expression is -41.
