Astandard showerhead in reyna's house dispenses 9 gallons of water per minute. reyna changed this showerhead to an energy-saving one. the equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new showerhead.
y = 3x
how much water does reyna save each day with the change in showerheads if she uses the shower for 8 minutes each day?
14 gallons
48 gallons
69 gallons
96 gallons

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.
