partial fractions
(7x^2-16)/(x^2-2x) solve by using partial fraction decomposition. i cant figure out how to do this because after i split up the bottom the A and B dont end up having an x^2 in order to equal the numerator of the original fraction. so confused!

Find the values of b such that the system has one solution. x^2 + y^2 = 36 y= x+b and then they give me an answer box b=_________ (smaller value) b=_________ (larger value) i have absolutely no idea how to even begin this and what they are asking. could some please help and ex...

yes but i still dont get the answer!!!

Use matrices to solve the system. (If the system has infinitely many solutions, express your answer in terms of c, where x = x(c), y = y(c), and z = c. If the system has no solution, enter NONE for each answer.) 5x+2y-z=2 x-2y+2z= -1 3y+z= -17 ive done tons of these but this o...
