Answer:
Picture 1:( x-2.5)²+(y+5.5)²=225
Picture 2:( x-4)²+(y-1)²=25
Step-by-step explanation:
Use the rule: ( x-p)²+(y-q)² =r
( p,q)is the coordinate of the center of the circle
r is the radius of the circle
Ok so remember
order of simplification
PEMDAS
parenthaseese
exponents
multiplicaton or division whichever comes first
addition or subtraction whichever comes first
ok so remmeber work from the left to right parenthasees first and work from inside to outer parenthasees
so first one
innermost parenthasees first so
first step is 2-4
subtract 4 from 2
second one
if xy=0 then assume x and y=0 so
(a+2)(b-9)=0
a+2=0
a=-2
b-9=0
b=9
so answe ris a=-2
b=9
third questions
innermost parenthaees first
subtract 4 from 2
ok
1. subtrac 4 from 2
2. a=-2, b=9
3. subtract 4 from 2
