5) since (x-a)^2+(y-b)^2=r^2
plug in (-5,2) as (a,b) and r=3
Making the equation:
(x+5)^2+(y-2)^2=9
6) (x-0)^2+(y-0)^2=r^2
since we have (0,5)
0^2+5^2=r^2
Final equation: x^2+y^2=25
Answer:
r= 2.5 and s=3
Step-by-step explanation:
2r plus 6r equals 8r
-3s and 3s cancell eachother out
and 14 plus 6 is 20
with leaves us with
8r=20
20 divided by 8 is 2.5
now we go back to the orginal problems
2 times 2.5 is 5
14 minus 5 is 9
9 divided by 3 is 3
so s=3
but to check this all you would use r=2.5 and s=3 in the othe equsion
6 times 2.5 is 15
and -3 times 3 is -9
15-9= 6
