6. let t : r^n -> rm be a linear transformation (a) if t maps r" onto r, what can you say about the relationship between m and n? (b) if t is one-to-one, what can you say about the relationship between m and (c)if t maps r" onto rm and is one-to-one, what can you say about the relationship between m and n?

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?
