Answer:
The first step for deriving the quadratic formula from the quadratic equation, 0 = ax2 + bx + c, is shown.
let's begin to solve this equation,,,
<h3>MORE BASIC INFORMATION </h3>
an equation having the maximum power of the variable equal to is called the quadratic equation the general form of quadratic equation is ax² + bx +c =0 where a,b,c are real numbers a ≠0 x is variable •
a quadratic equation can be solved by two method by factorization and by formula
by factorization a quadratic equation can be solved by factorization only when the product AC can be divided into two such part that it had the sum of the difference of the two part is equal to b
There are 7 6ths in 1 1/6
Each of those slots would have 1/6 wrote in them I believe
Let me know if I'm correct :)

Step-by-step explanation:
Which statement in the trailer is the hook?
A) Harry Potter seems at first glance normal, a boy living an unusual life with his dull and rather mean Dursley relatives.
B) However, on Harry’s eleventh birthday, he learns from a mysterious stranger, Rubeus Hagrid, that he is actually a famous wizard.
C) Forbidden by his uncle from seeking out his magical destiny, letters rain down inviting Harry to attend the magic school of Hogwarts.
D) What follows is an adventure story of intrigue, discoveries, and sacrifice.
In order of events:
A, C, B, D
A is where the story begins so it would be the best chose. It should catch you and make you want to know more. Also, the hook is usually the first sentence.
The line of best fit is a line that follows the direction of the dots. It doesn't have to be perfect, it's just a general line to represent the data. Sometimes there isn't a line of best fit (if there is no correlation). It normally touches most of the dots.
The slope is about 1/2 and the point where the line touches the y axis is at 40 so that means an equation could be y = 1/2x + 40
When the advertising expenditure (x value) is 18,000, substitute it into the equation above. y = 1/2(18,000) + 40 which equals y = 9,040 . This is the expected revenue.
Hope this helps!
Answer:
<em>The third side of the triangle must have a length between 23 yd and 41 yd.</em>
Step-by-step explanation:
<u>Triangle Inequality Theorem</u>
Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:
x + y > z
x + z > y
y + z > x
Combining the above inequalities, and provided y>z, the third size must satisfy:
y - z < x < y + z
We have to side lengths: y=32 yd and z = 9 yd, thus the range of possible values for the third side x is:
32 - 9 < x < 32 + 9
23 < x < 41
The third side of the triangle must have a length between 23 yd and 41 yd.
