Question

|-x|-|1,4-5x| при x=0,3

Answer 1

Ответ:

Сразу подставляешь 0,3 и получается:

|-0,3|-|1,4-5*0,3|

0,3-|1,4-1,5|

0,3-|-0,1|

0,3-0,1  и того 0,2

Answer 2

To find the value of the expression |-x| - |1.4 - 5x| when x = 0.3, we need to substitute the value of x into the expression and then perform the calculations step by step.

1. First, let's calculate the value of |-x| when x = 0.3: |-0.3| = 0.3

2. Next, let's calculate the value of |1.4 - 5x| when x = 0.3: |1.4 - 5(0.3)| = |1.4 - 1.5| = |-0.1| = 0.1

3. Finally, subtract the second result from the first result: 0.3 - 0.1 = 0.2

Therefore, when x = 0.3, the expression |-x| - |1.4 - 5x| equals 0.2.
