<h3>Answer is    -3</h3>

How I got that answer:

The graph shows the two points (0,-4) and (-2,2) are on the parabola. The x coordinates of both points are from x = 0 and x = -2 as given in the instructions. Compute the slope of the line through those points. The slope of this line is the exact same as the average rate of change from x = -2 to x = 0.

m = (y2 - y1)/(x2 - x1)

m = (2 - (-4))/(-2-0)

m = (2 + 4)/(-2-0)

m = 6/(-2)

m = -3

A negative slope means the line slopes downhill as you move from left to right. This is a negative average rate of change.

This is quite easy, but anyway:

In order, they are

3, 4, 4, 5, 5, 5, 5, 7, 7

7 - 3 = 4

Could it be 12? Difference between 16-13=3, 13-7=6. 4-3=1, 3-1=2. Seems as if for each column, difference between first and second row is one half the difference between the 2nd and third rows

Please answer asap if u know the answer!!!! completing a square. thank you!!!!
Tema [17]

Answer:

D

Step-by-step explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

To obtain this form using the method of completing the square.

Given

f(x) = 3x² - 24x + 10

We require the coefficient of the x² term to be 1 , thus factor out 3

3(x² - 8x) + 10

To complete the square

add/subtract ( half the coefficient of the x- term )² to x² - 8x

= 3(x² + 2(- 4)x + 16 - 16) + 10

= 3(x - 4)² + (3 × - 16) + 10

= 3(x - 4)² - 48 + 10

= 3(x - 4)² - 38, thus

f(x) = 3(x - 4)² - 38 ← in vertex form

Notebooks cost $ 1.20 each. This weekend they will be on sale for $ 0.80. What percentage is the sale
Rainbow [258]

From the information we have, we know that each book costs 1.20 dollars. So we shall say this price is at 100% .

Now we need to form an equation to get the percentage  when the books are sold at 0.80 dollars.

100% = 1.20

       x = 0. 80

Where x is the new percentage when the sale is at 0.80 dollars.

We cross multiply the equation:

1.20 *x = 0.80 * 100

1.2x = 80

x = 80/1.2

x = 66.7%

Round off 66.7 to the nearest tenth we get 67%

The notebooks are sold at 67% (of the original cost).
