Nevaeh has $0.80 worth of nickels and dimes. She has a total of u nickels and dimes altogether. Graphically solve a system of equations in order to determine the number
of nickels I, and the number of dimes, y, that Nevaeh has.

Is there a direction u in which the rate of change of f(x, y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.
