Question

identify the following curves.give in standard form:
1)16y^2-400+25x^2
2)16x^2-144=9y^2

Answer 1

solve for y

Answer 2

\[25x^2+16y^2=400\]
\[\frac{x^2}{16}+\frac{y^2}{25}=1\]

Answer 3

Ellipse

Answer 4

\[16x^2-9y^2=144\]
\[\frac{x^2}{9}-\frac{y^2}{16}=1\]

Answer 5

Hyperbola

Answer 6

is it the standard form y=mx+c ?
