A common misconception in statistics is confusing correlation with causation. If two events are correlated, it merely means that they share the same behaviour over time, but it doesn't imply in any way that those event are related by a common cause, or even worse, that one implies the other.
You can find several (even humorous) counter examples online. For example, if you plot the number of reported pirates assault against the global temperature in the last years, you'll se that temperature is rising (unfortunately...) while pirates are almost disappearing.
One could observe this strong negative correlation and claim that hotter climate has solved the pirate issue. Of course this is a joke, but it explains why you shouldn't confuse correlation with causation.
A is not part of the problem, and it's what makes the condition false. B is the opposite of the statement being proved. C is the condition, not the hypothesis. However, D is the statement we are trying to prove, or the hypothesis.
If y equaled 3, then we would plug 3 into the y spot on the equation. Therefore it would be 2x+4(3)=8. Now just solve.
2x+4(3)=8
2x+12=8
2x-12=8-12
2x=-4
2x/2=-4/2
X=-2

Answer:
y=-3x+3
Step-by-step explanation:
First you need to change the fractions to have the same denominator.
9 1/2 = 9 2/4 + 7 3/4
Then you just add across and simplify.
9 2/4 + 7 3/4 = 16 5/4 = 17 1/4.
You should get 17 1/4. Good luck!
