If you're trying to find the difference, your answer is 8C.
If this is just you messing around about today, that's good for conversation, and this isn't a place for conversation.
Step-by-step explanation:
The answer is square root 6/2
Answer:
y + 2 = -2(x - 3)^2
Step-by-step explanation:
We can see immediately that the vertex is at (3, -2).
The vertex form of the equation of a parabola is
y - k = a(x - h)^2.
If the parabola opened upward, the equation would be y + 2 = 2(x - 3)^2. But seeing that this particular parabola opens downward, the equation is
y + 2 = -2(x - 3)^2.
Check: Does the point (2, -4) satisfy this equation?
-4 + 2 = -2(2 - 3)^2 becomes -2 = -2(-1)^2, which is true.
5c - 7(2c - 4)
Distribute the 7 to everything inside the parenthesis.
5c - 14c + 28
Combine similar terms.
-9c + 28.
Hope that helped! :)
