Answer:
x^2 + y^2 = 4
Step-by-step explanation:
The center-radius form (formally called the standard form) of a circle is
(x-h)^2+(y-k)^2=r^2 where (h,k) is the center and r is the radius.
So if we replace (h,k) with (0,0) since the center is the origin and r with 2 since the radius is 2 we get:
(x-0)^2+(y-0)^2=2^2
Let's simplify:
x^2 + y^2 = 4
The answer are:
(-4,5)
(2,2)
(-1, -3)
(3,4)
(2,-1)
(-5,6)
You can not put a decimal to a decimal.So you meant to put a decimal to a fraction and the answer would be: 4.26 as decimal fraction = 426/100

Answer:
1 solution.
Step-by-step explanation:
-3d + 6 = 10
⇒ -3d = 10-6
⇒ -3d = 4
⇒ d = 
so, d =
