Answer:
8/12 = 2/3
Step-by-step explanation:
3x^2 + 4x - 21x - 28
x(3x + 4) - 7(3x + 4)
(3x + 4) (x - 7)
Answer: B).
the transformation (x, y) → (x, y- 4) , means the x-coordinate remains unchanged, while the y-coordinate has 4 subtracted from it, for example
the points on the diagram
A(1, 5 ) → A'(1, 5 - 4) → A'(1, 1)
B(4, 5) →B'(4, 5 - 4) → B'(4, 1)
C(4, 3) → C'(4, 3 - 4) → C'(4, - 1)
D(2, 2) → D'(2, 2- 4) → D'(2, - 2)
Answer:
(-4, -18).
Step-by-step explanation:
f(x = x^2 + 8x - 2 Completing the square on x^2 + 8x:-
= (x + 4)^2 - 16 - 2
= (x + 4)^2 - 18
- which is the vertex form of f(x)
The vertex of
(x - h)^2 + k is at (h, k)
So the vertex of f(x) is at (-4, -18)
