4. suppose the set {u, v} forms a basis for a subspace w, in r^n. let x = u+v and y u v. show [x. y is also a basis for w. (hint: use the basis theorem at the end of 2.9)

Pls me this is due today and i need i will make brainliest if you me answer correctly and i will report if you try to give me a dumb answer.

Write two subtraction equations that are equivalent to 5 + 12 = 17.

Determine the fraction of total interest owed. after the fourth month of a 12-month loan: the numerator is: {(n + ) + (n + ) + (n + ) + (n + )} = , and the denominator is: {(n) + (n + 1) + + (n + )} = . therefore, the fraction is numerator/denominator (to the nearest tenth) =
