Question

|4х+9|+6х при х =-4. СРОЧНО!!! ​

Answer 1

/4*(-4)+9/+6*-4=/-16+9/+(-24)=7+(-24)= -17

Answer 2

To find the value of the expression |4x + 9| + 6x when x = -4, follow these steps:

Step 1: Substitute the value of x into the expression. Step 2: Perform the calculations.

Given x = -4, substitute it into the expression:

|4(-4) + 9| + 6(-4)

Now, perform the calculations:

|(-16) + 9| + (-24)

Next, calculate the absolute value of (-16 + 9):

|(-7)| + (-24)

The absolute value of -7 is 7, so the expression becomes:

7 + (-24)

Finally, add 7 and -24:

7 - 24 = -17

Therefore, the value of the expression |4x + 9| + 6x when x = -4 is -17.
