Answer:
Parallel is undefined
Perpendicular is 0
Step-by-step explanation:
The line x = -42 is a vertical line through the x-axis. As such its slope is undefined. All parallel lines have the same slope and will also be undefined. Perpendicular lines will be lines horizontal through the y-axis. This means the slope of any perpendicular line to it will be 0.
D=(-infinity (the sign), infinity)
R=(-infinity, infinity)
<u>Answer:
</u>
The center, vertices and foci of the ellipse with equation 
respectively
<u>
Solution:
</u>
The equation of ellipse with centre (0, 0) in the form of 
--- eqn 1
Where,
x is the major axis
Centre (0, 0)
Vertices is 
Foci is 
where 
Now given that the equation of ellipse is
--- eqn 2
On dividing equation (2) by 36,
On comparing equations (1) and (2),
We get a = 3, b= 2
So centre of 
Vertices of 
Foci of 
Just replace each variable to what it is equal to. For example, replace the a variable in ab + cd with 2.
2 * -3 + 4 * -5 =
First, do the multiplication.
2 * -3 + 4 * -5 =
-6 + -20 =
Add up.
-6 + -20 = -26
So, the answer to this question is -26.
