Answer:

a = -7, b = -1, c = 1/3

Step-by-step explanation:

-x + 1/3 - 7x² ⇒ -7x² - x + 1/3

a = -7 b = -1 c = 1/3

The best approximation for the solution to this system of equations is (-2.2,-3)

Option C is correct.

Step-by-step explanation:

Solving the system of equations to get the exact value of x:

$y = -3\\y = x-0.8$

Let

$y = -3\,\,eq(1)\\y = x-0.8\,\,eq(2)$

Putting value of y from eq(1) into eq(2)

$-3=x-0.8$

$x=-3+0.8$

$x=-2.2$

So, Value of x is -2.2

The best approximation for the solution to this system of equations is:

x=-2.2 and y = -3

(-2.2,-3)

Option C is correct.

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

andreyandreev [35.5K]

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!
