Ok so when you distribute you get -60-12p+4p-20 then you will do -60+-20 which is -80 then you do -12p+4p which you get -8p then overall its -8p-80
There are several methods of rounding, but in this case the 'best' one is probably to round up. Rounding down suggests that Kathy actually ran faster.
<span>26.2 (mile) * 6.2 (minutes/mile) = 162.44 rounded up => 163 minutes.</span>
The correct option would be: y = 2x
You can check by replacing the variables with the given values.
Hope this helps!
The ones that will have the least area will be the ones that are the thinnest. That is to say, the ones with the greatest width to length (or length to width) ratios would have the smallest area.
The ones with the greatest area would be the ones with the smallest width to length (or length to width) ratios. They would be squares.
Answer:
![\frac{dy}{dx}=-\frac{x}{y}](https://tex.z-dn.net/?f=%5Cfrac%7Bdy%7D%7Bdx%7D%3D-%5Cfrac%7Bx%7D%7By%7D)
Step-by-step explanation:
Use implicit differentiation:
![x^2+y^2=25\\\\2x+2y\frac{dy}{dx}=0\\ \\2y\frac{dy}{dx}=-2x\\ \\\frac{dy}{dx}=-\frac{x}{y}](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3D25%5C%5C%5C%5C2x%2B2y%5Cfrac%7Bdy%7D%7Bdx%7D%3D0%5C%5C%20%5C%5C2y%5Cfrac%7Bdy%7D%7Bdx%7D%3D-2x%5C%5C%20%5C%5C%5Cfrac%7Bdy%7D%7Bdx%7D%3D-%5Cfrac%7Bx%7D%7By%7D)
Remember to treat "y" as a constant in implicit differentiation and include dy/dx.
