Determine the eccentricity of the ellipse given by 9x^2+16y^2-72x+64y-368=0

Step-by-step explanation:

The eccentricity of an ellipse is given by:

The given ellipse has equation:

We can rewrite this equation in standard form to obtain:

We compare to the general standard form equation:

to get:

We substitute into the eccentricity formula to get:

The eccentricity is 0.66 to the nearest hundredth

its 8

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
