In order to find if two lines are parallel or perpendicular or neither, following rules are used:
- If the slope of two lines is the same, the two lines will be parallel
- If the product of slopes of two lines is -1, the two lines will be perpendicular to each other.
- If none of the above two conditions is being satisfied, this mean lines are neither parallel nor perpendicular.
So the steps that must be followed are:
- Find the slope of the given lines.
- Use the values of the slope to check which of the above point is being satisfied and draw the conclusion accordingly.
What we are going to do is add
by
. The first thing we do is make common denominators for
and
:
. Now we add
by
:
. Now we make
a mixed number:
. Therefore, your answer is
. Hoped I helped. :)
The repeating decimal .99999 is equal to 1.
This can be proven by doing the following math
This is not a math problem, i think. you should post it on biology.
the answer is e.
i'd like to explain it to you, but sorry, i can't, because i'm not a native english speaker. i can't explain such a difficult problem in english.
The answer is 1
Hope that helps!
