No they aren't because they both can't be multiple by the same number
Answer:

Step-by-step explanation:
The additive inverse of a number (its "opposite") is what you add to the given number to get a sum of zero.

The equation of the vertical line is 
Explanation:
It is given that the vertical line passes through the points 
For vertical line, the slope is undefined.
Hence, 
Let us substitute the coordinate
in the equation
, we have,

Simplifying, we have,


where
and 
Substituting the values of a, b and c in the equation
, we have,

Thus, the equation of the vertical line is 
Answer: The correct choice is letter C.
Step-by-step explanation:
Cosine = adjacent/hypotenuse
In this triangle, you are looking for angle degree of cos X.
When finding an angle degree, you must use the inverse of whatever trig ratio you are using. In this case, you would use
.
The adjacent side from x is 12 and the hypotenuse is 15.
So you form your trig ratio which is your answer.
= 0.80
Answer:
the first one and the second one not the third one
