Answer:
D
Step-by-step explanation:
(-1) + (-1) = -2... so 500 times... it would be -500.
We can look at the graph
Vertex:
we know that vertex is the point where parabola changes it's shape
we can see that
vertex is at (0.5,-0.75)
Axis of symmetry:
we know that axis of symmetry of parabola is always x-value of vertex
we can see that
x-value of vertex is 0.5
so, axis of symmetry is

Formula for the function:
we know that this is graph of parabolas
so, we can use vertex formula of parabola

where
(h,k) is vertex
Here , we got
vertex as (0.5 , -0.75)
h=0.5 and k=-0.75
now, we can plug these values

now, we need to find 'a'
we can select any one point of parabola
and then we can find 'a'
We can see that one of point is (0,-1)
so, we can plug x=0 and y=-1




now, we can plug it back
and we get

now, we can expand it


so, option-D..........Answer
Answer: The answer is the second one from the top so the 1/3 with the 8 on the bottom.
Step-by-step explanation: No
Answer: 21
Step-by-step explanation: Using PEMDAS you add 6+6 to get 12. Then you multiply 7 and 12 which gets you 84. Then divide 84 by to get you 21.
