Let A = {2,3) and B = {2,3,4}. If a relation from A to B is defined by R = {(x, y) :x + y = 5), find R. a) R = {(x, y) : x + y = 5}
b) R = {(x, y) = x + y = 6)
c)R= {(x, y) : y = x^2}
d) R = {(x, y) : x=y}

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
