How did you get 18.6? on my calculator I typed in 3*log(4)/log(5)-log(4).Am I doing this wrong? solving it wrong?
Damon- yes, thank you
I did it a second time and got 1.98
I got 6.46
so its no limit which would just be infinity right?
wait, I still end up with the wrong answer. I end up with 4(x-5)^2/-120 - 9(y+2)^2=-120 9 can't go into -120 My procedure: (4x^2-40x)-(9y^2+36y)=-100 4(x^2-10x +4)-9(y^2 +4 +4)=-100+ 4(4)-9(4) 4(x-5)^2-9(y+2)^2=-120 (x-5)^2/-30 - ? 9 can't go into -120
okay, Thank you very much:)
