Question

|2x-5|+6x при x = —8​

Answer 1

|2x-5|+6x при x = —8​

|2*(-8)-5|+6x*(-8)= |-16-5|-48 =

= 21-48= -27

Answer 2

To evaluate the expression |2x-5|+6x when x = -8, we substitute -8 into the expression:

|2x-5| + 6x = |2(-8)-5| + 6(-8)

Now we simplify:

|2(-8)-5| = |-16-5| = |-21| = 21

Substituting back into the expression:

|2x-5| + 6x = 21 + 6(-8) = 21 - 48 = -27

Therefore, when x = -8, the value of |2x-5|+6x is -27.
