Question

solve for the asymptotes:

(y-1)^2/64 - (x+4)/49 = 1 ;

my answer is y = +/- 8/7(x+4) + 1, and they say its correct but what happens to the "64" you square?

Answer 1

* (x+4)^2

yes ur ans is right

Answer 3

Answer 4

the 64 and 49 are clues to the "box" in the center of the hyperbola

Answer 5

sqrt(64) is the distance from center to vertex, since its on the positive value

sqrt(79) is distance from center to the "missing" vortex if it had been an ellipse
