Answer:
[tex]P(x)=x^2+x-6[/tex]
Step-by-step explanation:
Quadratic Polynomial
Assume we have a polynomial factored as:
P(x)=a(x-m)(x-n)
Where m and n are the zeros of P(x).
Operating:
[tex]P(x)=a(x^2-(m+n)x+mn)[/tex]
Note the coefficient of x is the negative sum of the zeros and the independent term is the product of the zeros.
If we are given the zeros m=-3 and n=2, then:
[tex]P(x)=a(x^2-(-3+2)x+(-3)(2))[/tex]
[tex]P(x)=a(x^2+x-6)[/tex]
We can choose any value for a, for example, a=2:
[tex]P(x)=2x^2+2x-12[/tex]
For a=1:
[tex]P(x)=x^2+x-6[/tex]

Answer:
y = 4x + 40 and y = 40
Step-by-step explanation:
BAD QUESTION.
Believe it's y = 4x + 40 and y = 40. Others don't make sense. Sorry for bad explanation, but I'm a little unsure do to the question...
The second one is probably x > 10
Sorry in advance, try the question yourself if you can and check cause.

Sasha hikes into a canyon. She takes a break at the rest stations every 2/3 of a mile she descends.
If she started at sea level and has hiked down to the fourth rest station, what is Sasha’s elevation now?
Select all that apply.
a. -8/3 miles below sea level.
Sasha started at sea level and has hiked down to the fourth rest station.
Now sea level is 0.
Sasha takes a break at the rest stations every 2/3 of a mile.
This means she is down to 4 rest points means 4 times 2/3
This becomes =
But the answer will be in negative as she is below 0.
So, correct answer is: a. -8/3 miles below sea level.
Other way,
sea level is 0.....so if u go below sea level, u will end up with a negative number...and since she is hiking down, ur answer will be negative. The is a station every 2/3 mile....and if she passed 4 of them....
-2/3 * 4 = - 8/3 <=== her elevation....another answer could have been - 2 2/3, but that is not there
Sasha's elevation will be -8/3 miles below sea level.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that Sasha hikes into a canyon. She takes a break at the rest stations every 2/3 of a mile she descends.
Sasha started at sea level and hiked down to the fourth rest station. Now the sea level is 0. Sasha takes a break at the rest stations every 2/3 of a mile.
This means she is down to 4 rest points means 4 times 2/3
This becomes = 4 x ( 2 / 3) = 8 / 3
But the answer will be negative as she is below 0.
Therefore, Sasha's elevation will be -8/3 miles below sea level.

Given that f(x) = x2 – 12x + 27 and g(x) = x – 9, find f(x) · g(x) and
express the result in standard form.
Answer:
[tex]f(x)\cdot g(x)=x^3-21x^2+135x-243[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=x^2-12x+27\text{ and } g(x)=x-9[/tex]
And we want to find:
[tex]f(x)\cdot g(x)[/tex]
So, by substitution:
[tex]=(x^2-12x+27)\cdot (x-9)[/tex]
Distribute:
[tex]=(x^2-12x+27)(x)+(x^2-12x+27)(-9)[/tex]
Multiply:
[tex]=(x^3-12x^2+27x)+(-9x^2+108x-243)[/tex]
Rearrange:
[tex]=(x^3)+(-12x^2-9x^2)+(27x+108x)+(-243)[/tex]
Combine like terms:
[tex]=x^3-21x^2+135x-243[/tex]
Hence:
[tex]f(x)\cdot g(x)=x^3-21x^2+135x-243[/tex]

Which is the best description of an extraneous solution?
A solution that results in a true statement when substituted back into the original equation.
A solution that results in a false statement when substituted back into the original
equation.
A solution that is false for all absolute value equations.
A solution that is true for all absolute value equations.
Answer:
A solution that results in a false statement when substituted back into the original equation.
Step-by-step explanation:
An extraneous solution is one that arises in a solution of equations, but which on closer inspection is not a solution to the original equation. Therefore, they imply an error in the development of the solution of the equation, so they cannot be taken as a valid solution since, when replacing the result with the missing variable, the equation does not obtain the desired result.

How do you expand double brackets
Answer:
Step-by-step explanation:
Expanding double brackets is easy. Let me give u an example :
(x+5)(x+1)
so the way i do it is
1.Write the second bracket (x+1) twice :
(x+1) (x+1)
2. split the first bracket (x+5) like this :
x(x+1) +5(x+1)
3. Simplify
x*x = x²
x*1 = 1x
5*x = 5x
5*1 = 5
x² + 1x + 5x + 5 = x² + 6x + 5
so the final answer is gonna be x² + 6x + 5
in order to factorize it, u basically do the following :
1. Find two numbers, that multiply to give the last number (a.k.a 5 ) and add to give the middle number (a.k.a 6) The middle number is the sum, and the last number is the product.
so u write all the combo's that make the number 5 :
1 x 5
The two number's are gonna be 1 & 5, because 1 + 5 = 6 (the sum) and 1 x 5 = 5 (the product)
This example is easy since it doesn't include any negative numbers, so u just do = (x+1) (x+5) or (x+5) (x+1) same thing ;-;
I think u should just ask a teacher or watch a tutorial or smthn, this is like the worst explanation ever. But yeah once u know the method, you'll find expanding double brackets rly easy.
