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

The ratio of boys to girls in a group is 3 to 1 is there are 28 more boys then girls workout how many people their are it total
worty [1.4K]

Answer:

56 total

Step-by-step explanation:

Let the number of girls = x

Let the number of boys = 3x

x                      1

===       =    ==========

x + 28              3

Cross multiply

3x = x + 28                  Subtract x from both sides

3x - x = 28                   Combine

2x = 28                        Divide by 2

x = 28/2

x = 14

Girls = 14

Boys = 14 + 28 = 42

Is the ratio 3 to 1?

42/14 =  3/1 Yes it does

Total number

14 + 42 = 56
