finf x if [x] = 1.2?

Question

help

Answer 1

Find "x" when you have [x] = 1.2

*Keep in mind --- when an equation has an absolute value sign, you will have two solutions. One solution is positive, the other is negative.

1. [x] = 1.2

First: eliminate the absolute value sign....

x = 1.2 and -1.2

Sec: check the solutions...

1. x = 1.2

[1.2] = 1.2

1.2 = 1.2
True

2. x = - 1.2

[-1.2] = 1.2

1.2 = 1.2
True

Solution: 1.2 and -1.2

P.S. When your finding the absolute value of a negative number, the solution is always positive.

Answer 2

I assume those brackets should be straight:

find x if |x| = 1.2

in this case, x = 1.2 or -1.2

This is the definition of "Absolute Value".

Answer 3

X = 1.2 I'm pretty sure absolute value cannot be negative.

Answer 4

x = ±1.2

Answer 5

x=1.2

Answer 6

1.2 or -1.2

Answer 7

You'll have to tell us what [x] means before we can answer this one.
