Answer:
X^2 +Y^2 - 2X-4Y= 0
Step-by-step explanation:
From the circle eqn.
(x-a) ^2 +(y-b) ^2 =r^2
a=1, b= 2. r= 3
(x-1)^2 +(y-2)^2 =3^2
(x-1)(x-1)+(y-2)(y-2)=3^2
X^2 - 2x+1+y^2 -4y+4=9
X^2 +Y^2 - 2x-4y+5=9
X^2 +Y^2 - 2x-4y-4=0

Answer:
<em>The month-to-month contract will cost an extra $1356.</em>
Step-by-step explanation:
"An annual contract is $502.00/month with a 2-month penalty if you break the lease."
If you stay the whole year, and you pay $502 per month, you pay 12 * $502 = $6024 for the entire year.
"The month-to-month contract is $615.00/month."
If you stay the entire year, you pay 12 * $615 = $7380.
The difference is $7380 - $6024 = $1356
A. 11w=88
11w/11=88/11
w=8
b. 7u=210
7u/7=210/7
u=30
c. v÷81=9
v/81×81=9×81
v=729
d. c÷4=16
c/4×4=16×4
c=64
