Question

(y+ 1) - 2y, если y = 0,9​

Answer 1

Ответ:

(0,9+1)-0,9*2=0,9+1-0,9*2=1,9-1,8=0,1

Answer 2

Ответ:

(0,9+1)-0,9*2

0,9+1-0,9*2

1,9-1,8

0,1

Answer 3

To evaluate the expression (y + 1) - 2y when y = 0.9, we substitute the value of y into the expression and perform the calculation.

Let's substitute y = 0.9 into the expression: (0.9 + 1) - 2 * 0.9

Now, let's simplify the expression: (1.9) - 1.8

Finally, let's calculate the result: 1.9 - 1.8 = 0.1

Therefore, when y = 0.9, the expression (y + 1) - 2y evaluates to 0.1.
