Question

|-4|+|1-3x| при x=2.4 |x+1|-|-3| при x=1.1

Answer 1

4+|1-7,2|=4+6,2=10,2
2,1-3= -0,9

Answer 2

To evaluate the given expressions, simply substitute the values of x and perform the calculations:

1. For the expression |-4| + |1-3x| when x = 2.4: |-4| + |1 - 3(2.4)| = |-4| + |1 - 7.2| = 4 + 6.2 = 10.2

2. For the expression |x + 1| - |-3| when x = 1.1: |1.1 + 1| - |-3| = |2.1| - 3 = 2.1 - 3 = -0.9

So, the values of the expressions are:

1. |-4| + |1-3x| = 10.2 (when x = 2.4)
2. |x + 1| - |-3| = -0.9 (when x = 1.1)
