Explain why the two equations below have the same solutions.
x + 3y = −1
−2x − 6y = 2
a. the two equations have the same slope, so they have the same solutions.
b. the second equation is a multiple of the first equation, so they have the same solutions.
c. the graphs of the equations are parallel and do not intersect, so any solution of one is a solution of the other.
d. the lines are perpendicular, so they have the same solutions.

Based upon past experience, barry expects no overdrafts. he expects no 2nd copies of statements. barry estimates that he will use network atms about 5 times a month with either bank. barry decides in the end to choose eecu. assuming that both banks provide the necessary services equally well, and based upon the tables of fees given above, how much can barry reasonably expect to save annually by choosing eecu in this case over e-town bank? a. $72 b. $78 c. $144 d. $24
