The answer would be the third one because you cannot change the denominator and you can only add the numerators
Answer:

And if we convert to megahertz we got:

Step-by-step explanation:
For any mechanical wave we have the following general relationship:

where:
v represent the speed of the wave = 299790000 m/s
represent the wavelength for the radio station
f represent the frequency of interest
If we solve for the frequency we got:

And replacing the values we got:

And if we convert to megahertz we got:

Method 1: Realize that the desired equation will look exactly the same as the given equation 3x − 4y = 6, except that the constant will be different.
Thus, the equation of the new line is 3(-2) − 4(6) = C, where C comes out to 30.
Then the new line is 3x - 4y = 30.
