Without resorting to L'Hopitâl's rule,
![\displaystyle\lim_{x\to9}\frac{x-9}{x^2-81}=\lim_{x\to9}\frac{x-9}{(x-9)(x+9)}=\lim_{x\to9}\frac1{x+9}=\frac1{18}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Clim_%7Bx%5Cto9%7D%5Cfrac%7Bx-9%7D%7Bx%5E2-81%7D%3D%5Clim_%7Bx%5Cto9%7D%5Cfrac%7Bx-9%7D%7B%28x-9%29%28x%2B9%29%7D%3D%5Clim_%7Bx%5Cto9%7D%5Cfrac1%7Bx%2B9%7D%3D%5Cfrac1%7B18%7D)
With the rule, we get the same result:
![\displaystyle\lim_{x\to9}\frac{x-9}{x^2-81}=\lim_{x\to9}\frac1{2x}=\frac1{18}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Clim_%7Bx%5Cto9%7D%5Cfrac%7Bx-9%7D%7Bx%5E2-81%7D%3D%5Clim_%7Bx%5Cto9%7D%5Cfrac1%7B2x%7D%3D%5Cfrac1%7B18%7D)
620 I believe. Hope this helps
Answer: A
Step-by-step explanation:
Take the point (0, -6). The floor of 0 is 0, so normally it would be (0, 0). However, since the y coordinate is -6, not 0, we know it was translated down 6 units. Therefore, the answer is A.
