Mary and jolene are both growing tomatoes in their backyards to sell. jolene had 3 times as many as mary, but birds had eaten 6 before she picked them all. for the season they have a total of 54 tomatoes. how many tomatoes did mary grow?

The sum of the product of 4 and x and the product of 7 and y is 61. the sum of the product of 12 and x and the product of 21 and y is 61. what are the values of x and y?

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2

Find the directions in which the function increases and decreases most rapidly at upper p 0p0. then find the derivatives of the function in these directions. f(x,y)equals=x squared plus xy plus y squaredx2+xy+y2, upper p 0p0left parenthesis 1 comma negative 4 right parenthesis
