Question

i have this final and for the passed week we had a sub and i dont understand anything if someone is willing to help me even though its alot of questions i am willing to mail anyone five dollars for helping me i would offer more but thats all i have? my first question is 2x+3y+3z=5 4x+5y+3z=13 using matrices A.(5,13,13) B. (2,4,3) C. (1,2,-1)
D. (1,3,-2) my second question is given the hyperbola (x2/4)-(y^2/9)=1,find asymptotes. A. x=(1/3)y,x=(-1/13)y B.y=(1/3)x,y=(-1/3)x C.y=(3/2)x,y+(-3/2)x D.x=(3/2)y,x=(-3/2)y
