Question

Розв'яжить рівняння 1)Ixl=2,8 2)Ixl=-1,6​

Answer 1

Відповідь:

Покрокове пояснення:

|x| = 2.8

This equation states that the absolute value of x is equal to 2.8. Since the absolute value is always positive, x can be either 2.8 or -2.8.

Therefore, the solutions to the equation are x = 2.8 and x = -2.8.

|x| = -1.6

Here, you have an equation where the absolute value is equal to a negative number. However, absolute values are always non-negative (i.e., greater than or equal to zero). Therefore, there are no solutions to this equation.

The equation |x| = -1.6 has no solutions.
