why? well 6 is the hundredths place and you go over 1 to the 2 which is less than 5 so u dont change it
Y=9x because if you divided y by x all the numbers will equal to 9 which is proportional
1.03 Is approximately your answer
Answer:
X²+y²+2x-10y+18=0 is the equation of circle
Step-by-step explanation:
Eqn of circle is: (x-h) ²+(y-k)²=r²
At (h, k) =(-1,5) and r=8 where h, k are center and r is radius.
Eqn is :(x+1)²+(y-5)²=8²
Or, x²+2x+1+y²-10y+25=8
Or, x²+y²+2x-10y+18=0 is the equation of circle
All you dois times it three times
