Question

Найдите значение выражения: 3x-2|y-1|, y=-4

Answer 1

3x2|y-1| при x=-1,y=-4
3*(-1)-2*|-4-1|=-3-2*|-5|=-3-2*5=-3-10=-13

Answer 2

To find the value of the expression 3x - 2|y - 1| when y = -4, we substitute y = -4 into the expression:

3x - 2|(-4) - 1|

Now, calculate the value inside the absolute value:

3x - 2|-4 - 1| 3x - 2|-5|

The absolute value of -5 is 5, so the expression becomes:

3x - 2 * 5

Now, calculate the value:

3x - 10

That's the final value of the expression when y = -4.
