x= -1
|x + 1| - |x + 4| = 0 ∴ |x + 1| = |x + 4| ∴ x + 1 = -x - 4 ∴ 2x = -5 ∴ x = -5/2
x = 7
x=4
Abs(x) = x when x >= 0Abs(x) = -x when x < 0.In short, abs(x) is the distance from the origin to x, irrespective of whether it is to the left or right.
x= -1
5
|x + 1| - |x + 4| = 0 ∴ |x + 1| = |x + 4| ∴ x + 1 = -x - 4 ∴ 2x = -5 ∴ x = -5/2
When 'x' and 'y' both have the same sign.
The absolute value of 19 is 19. If x is positive , absolute x equals x.
zero. The absolute value of a number is just the positive version of that number, so the absolute value of x is x, and x minus x is zero.
In order to write f(x) = |x| + |x-2| without the absolute value signs, it it necessary to write it as a piecewise function.We must define f as follows:f(x) = -2x + 2, if x < 0f(x) = 2, if 0
x = 7
If: x+3 = 3+7 Then: x = 7
x=4
