Answer:
y = -3x + 1
Explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Subtract 3x from both sides of the equation:
3x + y = 1
3x (-3x) + y = 1 (-3x)
y = -3x + 1
y = -3x + 1 is your answer.

Answer:
Explanation:
Polarization In this case angle of incidence is not equal to angle of polarization, hence reflected light is partially polarized and transmitted light is also partially polarized. by reflection is explained by Brewster's law,
According to this when unpolarized light incident on glass plate at an angle is called as angle of polarizing the reflected light is plane polarized, and transmitted light is partially polarized. The plane of vibration of polarized light is having plane of vibrations perpendicular to plane of incidence.

I think i got it right not sure
A pebbled, uneven road would be easier to see at night because it minimizes the reflection of light from car’s light coming in the opposite direction. It is difficult to see when driving on the rainy day because the roadway reflects light from cars coming in the opposite <span>directions.</span>
Answer:
0.25 m
Explanation:
Given that,
The speed of sound, v = 330 m/s
The frequency of the note of the instrument, f = 1320 Hz
We need to find the wavelength of the sound wave.
We know that,
Wavelength, 
Put all the values,
So, the wavelength of the sound wave is equal to 0.25 m.
