For each equation, decide if it is always true or never true. x - 13 = x + 1

x - 3 = 2x - 3 - x

2(x + 3) = 5x + 6 - 3x

3(x - 5) = 2(x - 5) + x

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?
