(x-3)2+(y-4)2=24
2x-6+2y=24
2x-14+2y=24
2x=24+14-2y
2x=38-2y
x=19-y
Answer: 810
<u>Step-by-step explanation:</u>
There are 10 numbers to choose from. Since the 2nd digit and 3rd digit cannot repeat the number before it, they only have 9 numbers to choose from.
1st digit and 2nd digit and 3rd digit
10 choices x 9 choices x 9 choices = 810
let y = x^2
4y^2 -21y + 20 = 0
solve for y
then substitute back in to get x
The answer I believe is the third choice.
3, -2, -7, -12
These all fit into f(n)-5=f(n+1)
