Answer 1

Ответ:

Пошаговое объяснение:

| -4.5| = 4.5   |4.5|=4.5 ОТВЕТ :  Х= +/- 4,5

• Второе уравнение решения НЕ ИМЕЕТ - модуль не может быть отрицательным

Answer 2

1. |x| - 4.52

To solve this equation, you need to isolate the absolute value |x| on one side of the equation.

Start by adding 4.52 to both sides of the equation:

|x| = 4.52

Now, there are two cases to consider:

Case 1: x is positive or zero. In this case, |x| is equal to x because the absolute value of a non-negative number is itself.

So, x = 4.52

Case 2: x is negative. In this case, |x| is equal to the negation of x because the absolute value of a negative number is its positive counterpart with the sign reversed.

So, -x = 4.52

Now, multiply both sides by -1 to isolate x:

x = -4.52

So, the solutions to the equation |x| - 4.52 = 0 are x = 4.52 and x = -4.52.

2. |x| = -1.8

In this equation, the absolute value of x cannot be equal to a negative number. Absolute values are always non-negative. Therefore, there are no real solutions to this equation.
