<span>f(x) = x-2/3 and g(x) = 2-3x</span>
Answer:
B.
Step-by-step explanation:
Causation is often confused with correlation because they are so similar. B would mean that pollution is caused from something (lets say greenhouse gases for example) which then results in more cases of heart disease.
Causation is when the first variable may bring the second into existence or may cause the incidence of the second variable to fluctuate. So, causation is the capacity of one variable to influence another. Which, would make B, a suitable candidate.
notice, the denominator for each fraction is the same, thus the LCD is just 3.
The answer for the question is 21
