Question

|2x-9|+3x при х= -4​

Answer 1

|2x-9|+3x=|2*(-4)-9|+3*(-4)=17-12=5

Answer 2

если x= -4, то:

|2*(-4)-9|+3*(-4)=|-17|-12=17-12=5

Ответ:5

Answer 3

To find the value of the expression |2x - 9| + 3x when x = -4, we need to substitute -4 for x and then perform the calculations step by step.

First, replace x with -4 in the expression:

|2(-4) - 9| + 3(-4)

Now, perform the calculations inside the absolute value and multiplication:

|(-8) - 9| - 12

Now, simplify the absolute value:

|-17| - 12

The absolute value of -17 is 17, so:

17 - 12

Finally, subtract the values:

5

Therefore, when x = -4, the value of the expression |2x - 9| + 3x is 5.
