You can work a total of no more than 15 hours each week at your two jobs. Housecleaning pays $8 per hour and your sales job pays $10 per hour. You need to earn at least $130 each week to pay your bills.

Write a system of inequalities to represent this situation. DO NOT SOLVE.
Let x = # of hours housecleaning and y = # of hours at the sales job

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.
