We know:x^2+y^2+x−6y+9=0So, we complete the square as such:x^2+y^2+x−6y+9=x^2+x+y^2−6y+9=(x+1/2)^2+(y−3)^2=(1/2)^2=1/4
The answer is 3 :) hope helps

Answer:
Step-by-step explanation:
When x=3, y = ln(3-2) = ln(1) = 0.
:::::
When x=4, y = ln(4-2) = ln(2) ≅ 0.693.
:::::
When x=6, y = ln(6-2) = ln(4) ≅ 1.386.
Hi!
I think that you misspelled the question, and you mean that Oliver bought "ten", not "yen" stamps- yen is the currency of Japan.
So we have 10 stamps of 77 cents each:
10*77=770 cents
He has to pay 770 cents, or since 100 cents are one dollar, 7 dollars and 70 cents.
