Question

/-4/+/1-3х/. при х =2.4

Answer 1

I-4I+I1-7,2I= 4+6,2= 10,2

Answer 2

|-4|+|1-3x|=4+|1-3•2,4|=4+|1-7,2|=4+|-6,2|
=4+6,2=10,2

Answer 3

To solve the expression /-4/+/1-3х/ when x = 2.4, we need to substitute the value of x into the expression and perform the operations step by step following the order of operations (PEMDAS/BODMAS).

1. Start by replacing the variable x with its given value (x = 2.4): /-4/+/1-3 * 2.4/

2. Next, perform the multiplication: /-4/+/1 - 7.2/

3. Continue with the subtraction: /-4/+/ -6.2/

4. Finally, perform the absolute value operation: |-4| + |-6.2|

Now, we evaluate the absolute values: |-4| = 4 |-6.2| = 6.2

And the final result is: 4 + 6.2 = 10.2

So, when x = 2.4, the value of the expression /-4/+/1-3х/ is 10.2.
