Answer:
y = -(x - 2)^2.
Step-by-step explanation:
Vertex form is a(x - b)^2 + c where a is a constant and (b, c) is the vertex.
Here b = 2 and c = 0
So we have:
y = a( x - 2)^2 + 0
When x = 4 y = -4 so:
-4 = a( 4 - 2)^2
a = -4/2^2 = -1
So the required equation is
y = -(x - 2)^2.
It is equal to 7a
we can show that this is true because of distributive property
ab+ac=a(b+c)
2a+5a=a(2+5)=a(7)=7a
Answer:
Th answer is D
Step-by-step explanation:
can be added to 
to make it equivalent to 
.
Step-by-step explanation:
Let,
y be the term that can be added to given fraction.
Therefore;
Subtracting from both sides to find y
can be added to to make it equivalent to .
