Question

|2х-2|+|х| при х =1,3

Answer 1

2×1,3-2+1,3=

2,6-2+1,3=

0,6+1,3=

1,9

Answer 2

To find the value of the expression |2x - 2| + |x| when x = 1.3, we simply substitute the value of x into the expression and perform the calculations:

|2(1.3) - 2| + |1.3|

Now, let's solve it step by step:

1. Calculate the expression inside the first absolute value: 2(1.3) - 2 = 2.6 - 2 = 0.6

2. Calculate the expression inside the second absolute value: |1.3| = 1.3

So, the final expression becomes:

|0.6| + |1.3|

Now, the absolute value of any positive number is the number itself, and the absolute value of any negative number is the number with its sign reversed. Therefore, |0.6| is 0.6 and |1.3| is also 1.3:

0.6 + 1.3 = 1.9

Thus, the value of the expression |2x - 2| + |x| when x = 1.3 is 1.9.
