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
The period of the function is that distance where the function becomes equal again.
We have then:
Part 1:
The period of the function is:
T = 3
Part 2:
The period of the function is:
T = 4
Answer:
The period of functions 1 and 2 respectively are:
T = 3
T = 4

I'm sosssssssssssssssoooooooorrrrrrrrrryyyyyyyyyyyyyyyyyyyyy
Answer: -5x+y=6
Step-by-step explanation:
Given
Points on line 
The standard form of an equation is 
Using the two-point form of a line
<span>2x + 5y = 10
5y = -2x + 10
y = -2/5 x + 2
so slope = -2/5
</span><span>passes through the point (5, −4)
</span><span>y = mx + b
b = y - mx
b = -4 - (-2/5)(5)
b = -4 + 2
b = -2
equation
y = -2/5 x - 2
hope it helps
