Answer:

A quadratic function in standard form is converted to vertex form by completing the square. The first two terms are used to create a perfect square trinomial after a zero pair is added. The zero pair is found by taking half of the x-term coefficient and squaring it. The original constant term and the negative value of the zero pair are then combined.

Read this,it should help!

The standard form of a quadratic function is y = ax 2 + bx + c. where a, b and c are real numbers, and a ≠ 0. Using Vertex Form to Derive Standard Form. Write the vertex form of a quadratic function. y = a(x - h) 2 + k. Square the binomial. y = a(x 2 - 2xh + h 2) + k. y = ax 2 - 2ahx + ah 2 + k

(12,-9) and (-2,-2) in slope intercept form and if u want the points please explain how u got it

Montano1993 [528]

Answer:

$y= -\frac{1}{2} x-3$

Step-by-step explanation:

Slope intercept form :

y = mx + b

m is the slope

b is the y-intercept

Let's look for m, use the formula $\frac{(y_{1}-y_{2} ) }{(x_{1} -x_{2} )}$ to determine it.

$\frac{-9 - (-2)}{12 - (-2)}$ $= -\frac{1}{2}$

$y = -\frac{1}{2}x+b$

Now find b, we simply need to plug in one of our coordinates to get our answer.

(12, -9)

$-9=-\frac{1}{2} (12)+b$

Solve for b :

-9 = -6 + b

-3 = b

b = -3

Our slope intercept is :

$y = -\frac{1}{2}x - 3$

I need to model 2 equivalent fractions for 6 fifths

masha68 [24]

Six fifths = $\frac{6}{5}$ .
You can multiply the numerator and denominator by any number to find an equivalent fraction.
Two examples of equivalent fractions would be $\frac{12}{10}$ and $\frac{18}{15}$ .
Hope that helped you.

Louis wants to carpet the rectangular floor of his basement. The basement has a area of 768 square feet. The width of the baseme

pentagon [3]

Area=width*length. Let width=x ft, then length=3x ft, given the information in the problem. The area of basement=x*3x=768, 3x^2=768, x^2=256, x=16. The width is 16 feet. Therefore, length=3x=3*16=48 feet.
