Answer:
Step-by-step explanation:
The standard form equation for a circle is
![(x-h)^2+(y-k)^2=r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%2B%28y-k%29%5E2%3Dr%5E2)
where h and k are the coordinates of the center. Our center is given as (-6,7) and the radius is given as 9, so that information fits into our standard form like this:
and simplified, it looks like this:
![(x+6)^2+(y-7)^2=81](https://tex.z-dn.net/?f=%28x%2B6%29%5E2%2B%28y-7%29%5E2%3D81)
That's choice C
Answer:
D, Y=2x-4
Step-by-step explanation:
The easiest way to solve this is by substitution. Plug in 3 into the X of each equation to see if you get 2 as your outcome. Double check by doing the same with 8 and seeing if 12 is the outcome. Once you do this, problems like the one should be a piece of cake.
Answer:
80+16h≥256
Step-by-step explanation:
the 80 represents the $80 that Corinna already has
the 16h represents the amount of money made at the museum, with <em>h</em> being the number of hours worked
the inequality symbol is a greater than or equal sign because Corinna must have <em>at least</em> $256 to get the plane ticket, which means you either have to have the exact amount amount or more than the exact amount needed
Answer:
76%
Step-by-step explanation:
