Answer: B

Mathematics

Solve the problem.A tank initially contains 100 gal of brine in which 60 lb of salt are dissolved. A brine containing 4 lb/gal of salt runs into the tank at the rate of 8 gal/min. The mixture is kept uniform by stirring and flows out of the tank at the rate of 5 gal/min. Write, in standard form, the differential equation that models the mixing process.

A.  + y = 32
B.  + y = 20
C.  = 32 - y
D.  + y = 32

Find the missing coordinate to complete the ordered pair.y = 5x - 18(-4, )
