Question

5х-4(0,25х-1) при х=-1​

Answer 1

Ответ: 0

Пошаговое объяснение:

5х-4(0,25х-1) =5х - х + 4 = 4х + 4

при х = -1

4х + 4 = 4 * (-1) + 4 = 0

Answer 2

Ответ:

0

Пошаговое объяснение:

$5x-4(0.25x-1) =\\ 5x-(4*0.25x-4*1)=\\5x-(x-4)=\\5x-x+4=\\4x+4=\\-4+4=\\0$

Answer 3

To evaluate the expression 5x - 4(0.25x - 1) when x = -1, we substitute -1 for x in the expression and simplify:

5(-1) - 4(0.25(-1) - 1)

= -5 - 4(-0.25 - 1)

= -5 - 4(-1.25)

= -5 + 5

= 0

Therefore, when x = -1, the value of the expression 5x - 4(0.25x - 1) is 0.
