Answer:
Step-by-step explanation:
The vertex of this parabolas is at (2,-4)
Vertex form of equation is
where (h,k) is the vertex
h=2 and k=-4, plug in the values in the equation
the value of 'a' is 2 as per the given options
A.
Just by looking at the way the graph is pointing you can eliminate answer choices B and C because the set up of this equation will be x = not y =
So the set up of the equation is
x=2(y-(the y value of the vertex)squared+(the x value of the vertex)
by using this you can eliminate option D and see that the answer is A
Answer:?
The answer is Option B
We know that this inequality doesn't require any negative number division, there's no need to switch the ≤'s into ≥'s.
So now, all we have to do is subtract 25 from every number, giving us <u>5≤x≤50</u>
13825

12x12=144
