Step-by-step explanation:

Let x be the number.

Sum of five and 8 times a number: 8x + 5

Fifty plus one half of the number: 50 + (1/2)x

$8x+5=50+\frac{1}{2}x\\\\8x+5-5=50+\frac{1}{2}x-5\\\\8x=45+\frac{1}{2}x\\\\8x-\frac{1}{2}x=45\\\\\frac{16x}{2}-\frac{1}{2}x=45\\\\\frac{16x-x}{2}=45\\\\\frac{15x}{2}=45\\\\x=45*\frac{2}{15}\\\\x=3*2\\\\x=6$

The equation represents an ellipse. which point is the center of the ellipse? (−9, 5) (−5, 9) (5, −9) (9, −5)

Igoryamba

The point which is the center of the ellipse whose equation is; (y+5)²/121+(x-9)²/49=1 s in the task content is; (-5, 9).

<h3>Which point represents the center of the ellipse whose equation is given as; (y+5)²/121+(x-9)²/49=1?</h3>

It follows from convention that the equation of an ellipse usually takes the form;

(y-h)²/a²+(x-k)²/b²=1 in which case, the center of the ellipse is given by the point; (h, k).

On this note, By comparison of the actual equation and the standard equation, it follows that;

+5 = -h and consequently, h = -5,

-9 = -k and consequently, k = 9.

Ultimately, the point which is the center of the

ellipse is; (-5, 9).

Remark: The equation of the ellipse which is missing in the task content is; (y+5)²/121+(x-9)²/49=1
