Answer:
and 
Step-by-step explanation:
Given:
Equation 1:

Simplifying the above equation by dividing both sides by 100


Equation 2:

Simplifying the above equation by dividing both sides by 400.


Now the system of equation is:
(1a) 
(2a) 
Solving by elimination
Multiplying equation (2a) with 

(2b) 
Adding equations (1a) and (2b) in order to eliminate 

+ 
We get 
∴ 
Plugging
in equation (2a).

Adding
both sides.

∴ 
First Equation:

Second Equation can be written as:

Slope of first equation is -3/4 and slope of second equation is 3/4.
Slope of parallel lines must be equal, and slope of perpendicular lines are the negative reciprocal of each other. None of these conditions can be seen for given two equations.
So, the two lines are neither parallel nor perpendicular.
So correct option is C
Answer:
Lin = 8.2 m/s x 25 s =<u> 205 m </u> (<em>Finish Point)</em>
Elena = V = 250 m / 28 s <u>V = 8.93/s </u> (<em>Velocity</em>)
Diego = -8.1 m/s x 32 s =<u> -259.2 meters</u> (<em>Finish Point</em>)
Andre = V = -285 m /35 s V= -8.14ms (<em>Velocity</em>)
