Find the value of the expression x+|x|, if x=7, 10, 0, −3, −8. Simplify the expression x+|x|, if:

if x ≥ 0, then x + |x|=
if x < 0, then x + |x|=

14, 20, 0, 0, 0

Step-by-step explanation:

The notation indicates the absolute value of x, therefore it can be rewritten as:

if x 0

if x < 0

In this problem, we have the expression

Therefore, we can rewrite it as:

if x ≥ 0:

(a)

If x < 0:

(b)

So now we can substitute the given values into the two expressions:

x = 7 (positive value, so we use expression (a):

x = 10 (positive values, so we use expression (a):

x = 0 (zero, so we can use expression (a):

x = -3 (negative value, so we use expression (b):

x = -8 (negative value, so we use expression (b):

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

no
