Margaret took a trip to italy. she had to convert us dollars to euros to pay for her expenses there. at the time she was traveling, the conversion rate was represented by the function e(n)=0.72n, where n is the number of dollars and e(n) is the equivalent value in euros. later, she traveled to dubai and converted her remaining euros into the local currency, uae dirhams. at that time, the conversion rate was represented by the function d(x)=5.10x, where x is the number of euros and d(x) is the equivalent value in dirhams. which function can be used to convert n dollars directly to dirhams?
a) (d x e)(n) = 5.10(0.72n).
b) (d x e)(n) = (5.10x) x (0.72n).
c) (e x d)(n) = 0.72(5.10n).
d) (e x d)(n) = (0.72n) x (5.10x).

Asystem of linear equations with more equations than unknowns is sometimes called an overdetermined system. can such a system be consistent? illustrate your answer with a specific system of three equations in two unknowns. choose the correct answer below. a. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 6 b. no, overdetermined systems cannot be consistent because there are fewer free variables than equations. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 12 c. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 8 d. no, overdetermined systems cannot be consistent because there are no free variables. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 24
