9 would be answer. when you plug in the 9 to the equation you get 14=14 which is a true statement.
no solutions → C
The 2 given lines are parallel and never intersect thus no solution
Answer:
donkeey kongy
Step-by-step explanation:
You gave us the speed and the frequency, and you need the wavelength.
You were also nice enough to remind us that (fqy)x(lng) = speed.
So . . . F x W = 343 m/s
Divide each side by F :
W = (343 m/s) / F
W = (343 m/s) / (240 / s)
W = (343/240) m
<em>W = 1.429 meters</em>
