Answer:
Step-by-step explanation:
Given the system of equations:
You can pply Substitution method:
First you must solve for "y" from the first equation:
Therefore, the second and final step to solve the system of equations is to substitute the value of "y" into the second equation and solve for "x":

A. Surveying the students about their favorite type of math problem.
and
C. Sampling water for contaminants
The law of optics applicable in this scenario is the Snell's Law which states that the ratio of the index of refraction of two media is equal to the ratio of the sine of the angle of reflection and sine of the angle of refraction. In equation form:
n₁ / n₂ = sin b / sin a
