Answer:
Step-by-step explanation:
From the picture attached,
Two circles having centers A and B intersect each other at C and D.
We do a construction by joining points A and B to form a line segments AB.
From circle A,
AC ≅ AB ≅ AD [Radii of the circle A]
From circle B,
BC ≅ AB ≅ BD [Radii of the circle B]
Therefore, AC ≅ AD ≅ BC ≅ BD ≅ AB.
These segments of the quadrilateral are equal in measure.

Answer:
a (3,-1)
Step-by-step explanation:
The number that "completes the square" is the square of half the x-coefficient, (-6/2)^2 = 9. Rearranging the given function to include the square trinomial, we have ...
f(x) = x^2 -6x +9 -1 . . . . . . . here, we have 8 = 9 - 1
f(x) = (x -3)^2 -1 . . . . . . . . . . vertex form
Comparing this to the generic vertex form ...
f(x) = (x -h)^2 +k . . . . . . . vertex at (h, k)
we see that h=3 and k=-1.
The vertex is (h, k) = (3, -1).
Answer:
2)
collect like terms
move the constant to the right hand side and change its sign.
Subtract the numbers
Divide both sides of the equation by 8
