Answer:
The equation is (x + 1)^2 + (y + 2)^2 = 15
Center is at (-1, -2) and radius = √15
Step-by-step explanation:
2x^2 + 2y^2 + 4x + 8y - 20 = 0
Divide through by 2:-
x^2 + y^2 + 2x + 4y - 10 = 0
x^2 + 2x + y^2 + 4x = 10
Completing the square on the x and y terms:-
(x + 1)^2 - 1 + (y + 2)^2 - 4 = 10
(x + 1)^2 + (y + 2)^2 = 10 + 1 + 4
(x + 1)^2 + (y + 2)^2 = 15
Answer:
No
def of independent is P(A)*P(B) = P(A and B)
.2*.4 = .08 thus dependent
Step-by-step explanation:

3(b+2)+2(b-3)=-5
3b+6+2b-6=-5
5b=-5
b=-1
Answer:
As X → - ∞ , y → ∞ and as x→ ∞ , y → ∞
<h3>
option c is the correct option.</h3>
Step-by-step explanation:
let f(x) = y = 3x² - 5x + 2
y = 3x² - 5x + 2
= x ( 3x - 5 ) + 2
y = ∞ ( 3 ( ∞ - 5 ) ) + 2
= ∞ (∞ ) + 2
y = ∞
y → ∞ as x → ∞
Now,
as x → - ∞
y = x ( 3x - 5 ) + 2
= ∞ ( 3 ( - ∞ ) - 5 ) + 2
= - ∞ ( - ∞ ) + 2
∞² + 2 = ∞
Hence , Option C is the correct answer.
