Find the x-intercept form the line represented by this equation. 5x+7y=3

krek1111 [17]

Answer:

A. (3/5, 0).

Step-by-step explanation:

The x intercept occurs where y = 0, so we have:

5x + 7(0) = 3

5x = 3

x = 3/5 so the required point is (3/5, 0).

Which is the equation of an ellipse centered at the origin with foci on y-axis, major axis of length 20 and minor axis of length

fenix001 [56]

Centered at the origin means (h,k) =(0,0)

Length of major axis, 2a = 20

That gives, a =10

Length of minor axis, 2b =18

That gives, b=9

And since focii is on the y axis, so its a vertical ellipse of the form

$\frac{(x-h)^2}{b^2} + \frac{(y-k)^2}{a^2} =1$

Substituting the values of a and b, we will get

$\frac{x^2}{81}+\frac{y^2}{100}=1$
