Question

Найдите значения 3х-2¦y-1¦ при х=-1, y=-4

Answer 1

3x-2|y-1| = 3*(-1)-2*|-4-1| = -3 - 2*(4+1) = -3 - 2*5 = -13

Answer 3

To find the value of the expression 3x - 2|y - 1| when x = -1 and y = -4, simply substitute the given values into the expression and perform the calculations step by step.

Step 1: Substitute x = -1 and y = -4 into the expression: 3x - 2|y - 1|

Step 2: Calculate the absolute value of (y - 1): |(-4) - 1| = |-5| = 5

Step 3: Substitute the absolute value result into the expression: 3x - 2|y - 1| = 3(-1) - 2(5) = -3 - 10 = -13

So, the value of the expression 3x - 2|y - 1| when x = -1 and y = -4 is -13.
