Answer:
Step-by-step explanation:
You're given a coordinate in the form of (x, y) and you're also given the vertex in the form of (h, k). We will use those in the vertex form of the equation
and solve for a. Filling in:
which simplifies a bit to
and a bit more to
. Add 3 to both sides to get
-8 = 4a so
a = -2
The equation, then, is

Answer:
D
Step-by-step explanation:
The function
has value F(2) when x = 2 is substituted.

840=2 times 2 times 2 times 3 times 5 times 7
Answer:
A
Step-by-step explanation:
-4u - w = u + 6w
-4u = u + 7w (Add w to both sides)
-5u = 7w (Subtract u from both sides)
w =
(Divide both sides by 7)
Answer:
you multiply all of those answers
