Question

|5 - 8х|+2х при х = -7​

Answer 1

Ответ:

Пошаговое объяснение: модуль>0.

5-8(-7)+2(-7)=5+56-14=61-14=47.

модуль <0.

-(5+56)+2*(-7)=-61-14=-75.

Answer 2

To find the value of the expression |5 - 8x| + 2x when x = -7, we substitute -7 into the expression and calculate:

|5 - 8(-7)| + 2(-7)

First, we evaluate the expression inside the absolute value:

|5 - 8(-7)| = |5 + 56| = |61| = 61

Now, we substitute this value back into the original expression:

|5 - 8x| + 2x = 61 + 2(-7) = 61 - 14 = 47

So, when x = -7, the expression |5 - 8x| + 2x evaluates to 47.
