graph 4x^2+y^2=9 what are its lines of symmetry?
In a circle, you must have x^2 and y^2. The signs must be positive and the coefficients must be the same.
In a parabola, you must have x and y^2 or y and x^2. Then you know the graph is a parabola.
n a hyperbola, you must have x^2 and y^2 but one of them is negative.
these are the answer choices. im still a little confused.
sorry power went out
So now we know that 4x^2 + y^2 = 9 is an ellipse because we have x^2 and y^2. Both are positive and the coefficients are different.
So now your job is to rearrange it so it is in this form: 1 sec
\[\frac{ x^2 }{ a^2 }+\frac{ y^2 }{ b^2 }=1\]
how do I rearrange them?
Do you notice that the right side has to be 1?
you're saying the same things that the one guy was saying for the other question -,- its almost as if you're copying & pasting. I really need help asap.
exaclty he ex[plains it well
so what is the answer?
the first one
Thank you! can you help me with another one?
