How do you find the AOS and vertex of a quadratic?

Mathematics

Answer:

The standard form of a quadratic is y = ax^2 + bx + c.

  • In this equation, the formula for the axis of symmetry is x = \frac{-b}{2a}.
  • You know that the center will always be along that line, and you've got the x-coordinate already, so just plug that in and get the y-coordinate out for the center.

The vertex form of a quadratic is also helpful, y = a(x-h)^2 + k.

  • In this equation, the formula for the center is (h, k), and the axis of symmetry is x = h! That's even easier!

Pls help???????? need to have an explanation also
Ratling [72]

Answer:

I would say the answer is 40 cookies

Step-by-step explanation:

The reason I say this is because if you write out the amount of cookies she can make with 6 cups of flour, you would get 30/6. 30 and 6 are both divisible by 6, so if you divided both by 6 you will get 5/1. 1 times 8 is 8, so if you multiply 5 by 8 you will get 40 cookies.

Hope this helped!
