Is W a subspace of the vector space? If not, state why. (Select all that apply.) W is the set of all nonnegative functions in C(−[infinity], [infinity]). W is a subspace of C(−[infinity], [infinity]). W is not a subspace of C(−[infinity], [infinity]) because it is not closed under addition. W is not a subspace of C(−[infinity], [infinity]) because it is not closed under scalar multiplication.

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?

Which graph represents the linear function below? y-4= (4/3)(x-2)
