Hello!
<span>The constant of variation is xy. XY=23. If X=7 then Y=23/7.
</span>
So as we can see, the stated inverse variation can be represented as the equation y = k/x. ===> k = 23 & x = 7 ⇒ y = 23/7. <====
I Hope my answer has come to your Help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead! :)

Let's take a look at D:
<span>D) y = (x-1)^2 - 16 Compare this to
y = (x-h)^2 + k This is the std. equation of a parabola in vertex form.
You can see, by comparison, that h=1 and k= -16; these are the coordinates of the vertex, clearly shown in the diagram.
Since the coefficient of (x-h)^2 is +1, the graph opens upward (which the given graph confirms), and is neither compressed nor stretched vertically.</span>
The answer is 0.6616
Hope it helped :)
The answer is a because when u divide that number by 6 u get a whole number
