1. in parts a and b, determine whether the set w is a subspace of r² with the standard operations. justify your answer. (a) w = {(x1,c2,4): x1 and 22 are real numbers } (6) w = {(s, t, s +t): s and t are real numbers} 2. determine whether the set of vectors p2 is linearly independent or linearly dependent. s = {-1+x²,5 + 2x} 3. determine whether the set s = {(5,6,5), (2,1, -5), (0, -4,1)} spans r. 4. determine whether s is basis for r. s = {0,0,0), (1,5,6), (6, 2, 1)}

answear:

a

step-by-step explanation: a

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
