Answer:
To figure out if 2 lines are parallel, compare their slopes. You can find the slope of a line by picking 2 points with XY coordinates, then put those coordinates into the formula Y2 minus Y1 divided by X2 minus X1. Calculate the slope of both lines. If they are the same, then the lines are parallel.

Answer:
6.96%
Step-by-step explanation:
Assuming that the total number of races who did not finish the race are the ones who gave up and were disqualified:
(14+4)/230 = 0.06957
convert to percentage 0.06956*100= 6.957%
Tan 2 x-2 tan x=0
Tan x (tan x-2 ) =0
A tan x=0 —> x=0 and x =K π
B tan x=2 —> x=63.43 +k180 deg
Answer: (x + 0, y − 4), 180° rotation, reflection over the y-axis.
