This equation can be written as
(v-8)(v+5)/ (v-8)(v-3)
= v+5/v-3
Time = 3 miles / (20 mph - wind velocity)
time = 2 miles / (20 mph + wind velocity)
3 miles / (20 mph + wind velocity) = 2 miles / (20 mph - wind velocity)
3/2 = (20 mph + wind velocity) / (20 mph - wind velocity)
1.5 = (20 mph + wv) / (20 mph -wv)
30 mph -1.5wv = 20 mph -wv
10 mph = 2.5 wv
wind velocity = 4 mph
Answer:
y =3x-7
Step-by-step explanation:
y - 2 = 3(x-3)
y -2 = 3x -9
y = 3x-7
I am not sure if it is A or B but it is definitely one of those because they have different y-intercepts. You have a 50/50 chance if you want to guess or you can graph it out and get an exact answer. Hope this helps!
