Answer: Option A
Explanation: The lights that is incident on a mirror will be reflected back as it is a smooth surface and it reflects back the light.
the light will be reflected by the same angle as it was incidented. The angle of incidence can be defined as the angle by which the light ray falls on the surface of the mirror.
The angle by which the light reflects back is known as the angle of reflection. Being a smooth surface light ray is reflected back.
Answer:
0.00139746127868
Step-by-step explanation:
just use a coculator
So than there are
1x -5y =15
-1x +5y = -15
--------------------assuming term by term we get
0 0 = 0
so from what result that this system has infinitely many solutions
hope helped
I believe you would Add like terms so 4x^2-4x-3
