Is this relation a function? Justify your answer 10 5 O A. Yes, because the number of x-values is the same as the number of y values O B. Yes, because every x- and y-value is positive. c. Yes, because every x-value has a single p-value D. No, because two points with the same y-value have different values

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
