Answer: center (1;0), radius = 2
Step-by-step explanation:
x² – 2x + 5+ y² = 8
x² – 2x + 5+ y² = x² – 2x + 1 + 4 + y² = (х-1)² +4 + y²
(х-1)² +4 + y² = 8
(х-1)² + y² = 8 - 4 = 4
(х-1)² + y² = 2²
center (1;0), radius = 2
Answer:

Step-by-step explanation:
?
Answer:
Step-by-step explanation:
The first answer a, is not a linear function because of the first term, 2√(x), this is basically 2(x^(1/2)) which means that it is not linear
B is linear because there are no exponents in any of the variables.
C is not linear because it forms a circle when graphed
D is linear because there are no exponents in any of the variables.
E is linear because there are no exponents in angy of the variables.
F is linear because there are no exponents in any of the variables.
G is not linear because it is a quadratic equation.
