Question

1) 0,8b-2,при b=-62) -0,8b-2,при b=-6​

Answer 1

Ответ:

0,8×(-6)-2=-6,8

-0,8×(-6)-2=2,8

Answer 2

To evaluate the expressions:

1. 0.8b - 2, when b = -6
2. -0.8b - 2, when b = -6

You simply substitute the value of b with -6 and perform the calculations.

1. 0.8b - 2, when b = -6: 0.8(-6) - 2 -4.8 - 2 -6.8

So, when b = -6, the expression 0.8b - 2 evaluates to -6.8.

2. -0.8b - 2, when b = -6: -0.8(-6) - 2 4.8 - 2 2.8

So, when b = -6, the expression -0.8b - 2 evaluates to 2.8.
