Step-by-step explanation:
To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you use the process of completing the square. Let's see an example. Convert y = 2x2 - 4x + 5 into vertex form, and state the vertex. Equation in y = ax2 + bx + c form.

Answer: 25% of 40 or 0.25 of 40 is 10.
Step-by-step explanation:
Basically you have to divide 40 by 10 because 1/4 of 100 is 25. 25 is 1/4 of 100.
So knowing this 40/0.25 is equal to 10. This is why 0.25 of 40 is 10.
There is a rule:
One input(x-value) can only have one output(y-value) in order to be a function.
If one input has more than one output, it is not a function.
(This doesn't apply to outputs, one output can have more than one input and still be a function)
(2,10),(4,15),(6,20),(8,25)
This is a function because each input only has one output.
Your answer is A
Answer:
(2, 1)
Step-by-step explanation:
A line that passes through the origin and has a slope of 1/2 can be best represented as y = 1/2x
it starts at the origin
goes 2 units to the right
1 unit above
2 units to the right + 1 unit above = (2, 1)
Final Answer: (2, 1)
