Question

|-4 -5x| + |-3| при x=1,1

Answer 1

|-4 - 5,5| + 3 = 1205

Answer 2

To evaluate the expression |-4 - 5x| + |-3| at x = 1.1, we substitute the value of x into the expression and calculate the absolute values first, then perform the addition.

|-4 - 5x| + |-3| = |-4 - 5(1.1)| + |-3|

Now let's calculate the absolute values:

|-4 - 5(1.1)| + |-3| = |-4 - 5.5| + |-3|

Next, perform the subtraction and find the absolute values:

|-4 - 5.5| + |-3| = |-9.5| + |-3| = 9.5 + 3 = 12.5

Therefore, when x = 1.1, the expression |-4 - 5x| + |-3| equals 12.5.
