Choose the correct equation in point slope form for the line that passes through the point with the given slope.
Airida [17]
Here you should use the equation y - y1 = m(x - x1), where (x1, y1) are a point and m is the slope:
y - 1 = -3(x - 2)

I'm not sure if perhaps there's an error in the question or the re-typing but none of the answers stated above match the solution.

12-3 (2w+1)=7w-3 (7+w)
n200080 [17]
12-3(2w+1)=7w-3(7+w) \\ \\ 12-6w-3=7w-21-3w \\ \\ 9-6w=4w-21 \\ \\ -6w-4w=-21-9 \\ \\ -10w=-30 \\ \\ \boxed{x=\frac{-30}{-10}=3}

The inverse variation equation shows the relationship between wavelength in meters, x, and frequency, y
Cerrena [4.2K]

We have been given that the inverse variation y=\frac{3\times 10^8}{x} shows the relationship between wavelength in meters, x, and frequency, y. We are asked to find the wavelength for radio waves with frequency 3\times 10^9.

To find the required wavelength, we substitute y=3\times 10^9 in our given equation and solve for x as:

3\times 10^9=\frac{3\times 10^8}{x}

x=\frac{3\times 10^8}{3\times 10^9}

We can see that both numerator and denominator has 3, so we can cancel it out.

x=\frac{1\times 10^8}{1\times 10^9}

Using quotient rule of exponents \frac{a^m}{a^n}=a^{m-n}, we will get:

x=1\times 10^{8-9}

x=1\times 10^{-1}

Therefore, the wavelength for radio waves would be 1\times 10^{-1} meters and option B is the correct choice.
