    the problem is \[4x ^{2}+9y ^{2}-8x-18y-23=0\] find the center and separate the values with a comma

    Are you telling me that center (1,1) Major axis vertices (4,1) , (-2,1) Minor axis vertices (1,3) , (1,-1) Foci (1 + sqrt 13,1) , (1 - sqrt 13,1) were wrong??? I would like to know because I am sure it is correct.

    well on the assignment i was doing, i can only miss 2 questions. 3 were wrong. so i exited out of the assignment because i was going to fail it anyways. so then i had to start over. and now it's not always the same questions

    Well this one was the same one... I think on the second one you didn't type it in correctly. I think you missed a sign. Now when it comes to the sqrt 13, I don't know if it want you to use a calculator and estimate or use the sqrt 13.. You will have to know which one they want.

    I will stick with you until you get enough correct if you want. If not, I will move on

    you have to figure out the square & round it. but yeah, it's the same one. but it's very uncommon that it will repeat questions. i have no idea at all how to do any of this. kinda the reason why i have been on it for almost a month now

    How about (-1,6) .. does it say it is an hyperbola?

    find the equation that represents the asymptotes of this hyperbolas A.\[y=\pm2x\] B.\[y-6=\pm1/2(x+1)\] C.\[y-6=\pm2(x+1)\] D.\[y=\pm1/2x\]

    Did you put it in... I don't think it is correct. I forgot about the center..
