Question

При каких значениях x < -x? Помогите пожалуйста!

Answer 1

Если х является отрицательным числом, ведь минус на минус дает плюс. 

Answer 2

Values of x where x < -x

The inequality x < -x holds true when x is a negative number. This is because when x is negative, its absolute value is greater than the negative of itself. Therefore, any negative value of x satisfies the inequality x < -x.

Source: According to the source, "x < -x" is true when x is a negative number.

Examples of Inequalities

Here are some examples of inequalities involving logarithmic functions:

1. \(log_3(x^2+4)=log_3(4x)\) - Solution: x = -1

2. \(log_28=log_{16}(x)+2\) - Solution: x = 16

3. \(log_2(2x^2)-5=log_2(x) +log_2(x-5)\) - Solution: x = \(\frac{16}{3}\)

4. \(log_9(x+4)\geq log_9(2x)^2\) - This is an inequality to be solved.

Source: The provided examples illustrate different logarithmic inequalities and their solutions.
