<span>draw a straight line through those points. that's your line of reflection. now you have only to figure out which of those equations corresponds to it.
So it y=x</span>

Answer:
Step-by-step explanation:
The speed against the wind is ...
4680 mi/(8 h) = 585 mi/h
The speed with the wind is ...
5720 mi/(8 h) = 715 mi/h
The speed of the airplane in still air is the average of these speeds:
(585 +715)/2 = 650 mi/h . . . speed in still air
The speed of the wind is the difference between the airplane speed and the speed in the wind:
715 -650 = 65 mi/h . . . speed of the wind
_____
<em>Additional comment</em>
If p and 'a' represent the speeds of the plane and the air, the speeds with and against the wind are ...
p + a = with
p - a = against
If we average these, we get ...
((p +a) +(p -a))/2 = (with + against)/2
p = (with + against)/2 . . . . . . . the formula we used above
The millers will travel 240 miles in six hours.
The answer is C. Hope this helps
Answer:
x = 13
Step-by-step explanation:
In a triangle, all the angles equal 180 so
2x + 5x - 7 + 6x + 18 = 180
combine like terms
13x + 11 = 180
13x = 169
x = 13
