Question

У=2(х-3)+5(0,2х-1). знайти значення у,якщо х= -3

Answer 1

Ответ:

Объяснение:

y=2x-6+x-5

y= 3x-11

y= -9-11

y= -20

Answer 2

To find the value of y (у) when x (х) is equal to -3, you need to substitute -3 for x in the equation and solve for y.

The equation is: У = 2(х-3) + 5(0.2х-1)

Let's plug in x = -3:

У = 2((-3) - 3) + 5(0.2(-3) - 1)

Now, perform the calculations step by step:

У = 2(-6) + 5(-0.6 - 1)

У = -12 + 5(-1.6)

У = -12 - 8

У = -20

So, when x = -3, y (У) will be -20.
