Question

|1-2x|-|x| если х=0,7

Answer 1

|1-2*0,7|-|0,7|=|1-1,4|-0,7=|-0,4|-0,7=0,4-0,7=-0,3.

Answer 2

|1-1,4|-|0,7|
|-0,6|-|0,7|
0,6-0,7
Ответ:-0,1

Answer 3

To evaluate the expression |1-2x|-|x| when x=0.7, we substitute 0.7 for x and simplify as follows:

|1-2(0.7)|-|0.7| = |1-1.4|-0.7 = |-0.4| - 0.7 = 0.4 - 0.7 = -0.3

Therefore, when x=0.7, the value of |1-2x|-|x| is -0.3.
