1/x + 1/4 = 7/12 solve for x

Licemer1 [7]

Given equation is
$\frac{1}{x} + \frac{1}{4} = \frac{7}{12}$

We can solve it by subtracting 1/4 both side
$\frac{1}{x} + \frac{1}{4} - \frac{1}{4} = \frac{7}{12} - \frac{1}{4}$

$\frac{1}{x} = \frac{7}{12} - \frac{1}{4}$
                          $= \frac{7 - 3}{12}$
                          $= \frac{4}{12}$
                          $= \frac{1}{3}$

So $\frac{1}{x} = \frac{1}{3}$
On comparing x = 3.

SO the solution of equation is x = 3

Find the standard form of the equation of the ellipse with the given characteristics. Vertices: (4, 0), (4, 14); endpoints of th

saul85 [17]

Answer:

The standard form of the ellipse is $\frac{(x-4)^{2}}{9} + \frac{(y-7)^{2}}{49} = 1$ .

Step-by-step explanation:

The major axis of the ellipse is located in the y axis, whereas the minor axis is in the x axis. The center of the ellipse is the midpoint of the line segment between vertices, this is:

$(h, k) =\frac{1}{2}\cdot V_{1} (x,y) + \frac{1}{2}\cdot V_{2} (x,y)$ (1)
