Question

|-а|=4 Линейные уравнение с модулем

Answer 1

Ответ:

Пошаговое объяснение:

По свойству модуля |a| = |-a|

|-а|=4

|a| = 4

a = 4

a = -4

Answer 2

Відповідь: |-4|=4

Покрокове пояснення: если в модулях -4 или -5 и т.д например |-5|=5 то если забрать модули то всегда будет положительное число а если |5|=5 так просто переписываем число какое в модулях.

Answer 3

Solving the Equation |-a| = 4

To solve the equation |-a| = 4, we can consider two cases: when a is positive and when a is negative.

Case 1: a is positive If a is positive, then |-a| = a. So, the equation becomes a = 4.

Case 2: a is negative If a is negative, then |-a| = -a. So, the equation becomes -a = 4.

Now, let's solve each case separately.

Case 1: a is positive

In this case, the equation becomes a = 4. Therefore, the value of a is 4.

Case 2: a is negative

In this case, the equation becomes -a = 4. To solve for a, we can multiply both sides by -1 to get a = -4.

So, the solutions to the equation |-a| = 4 are a = 4 and a = -4.
