If the equation is solved, which is true? (Round to the nearest tenth as needed) If -2 + x = -3, then x = -1.0 If x + -2 = -3, then x = 1.5 If -2 - x = -3, then x = -5.0 If -2 + x = -3, then x = -5

A) -2 + x = -3 is equal to x = -1 is True!

Step-by-step explanation:

-2 + x = -3

+2         +2

x = -1

x = -1

Correct

x -2 = -3

 +2    +2

x = -1

x = 1.5 is False

-2 - x = -3

+2        +2

-x = -1 or x = 1

x = -5 is False

-2 + x = -3

+2        +2

x = -1

x = -5 is False

Given:

The given vector is:

To find:

The unit vector in the direction of the given vector.

Solution:

If a vector is , then the unit vector in the direction of the this vector is

Where,

We have,

Here, and . So,

Now, the unit vector in the direction of the given vector is:

Therefore, the required unit vector is .
