Ariel is taking a medicine for a common cold. the table below shows the amount of medicine f(t), in mg, that was present in ariel's body after time t: t(hours): 1 | 2 | 3 | 4 | 5 f(t) (mg): 236 | 223.73 | 211.65 | 200.22 | 189.41 christina was administered 250 mg of the same medicine. the amount of medicine in her body f(t)after time t is shown by the equation below: f(t) = 250(0.946)^t which statement best describes the rate at which ariel's and christina's bodies eliminated the medicine? ariel's body eliminated the antibiotic faster than christina's body. ariel's body eliminated the antibiotic at the same rate as christina's body. ariel's body eliminated the antibiotic at half of the rate at which christina's body eliminated the antibiotic. ariel's body eliminated the antibiotic at one-fourth of the rate at which christina's body eliminated the antibiotic.

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
