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)

Distance=slopeslope is -2/4which equals-1/2the distance between these two points is -1/2

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
