After factorization, the absolute value of the variable 'x' is 9.
What is factorization method?
The factorization method is used for the quadratic based equation whose highest degree is either two or more than two. Depending upon the degree of the variable, the number of factors are calculated. And by substituting the calculated value to check whether the answer is correct or not.
According to the question, the given linear equation is: |2x - 4| = 15
Now, to calculate the value of the variable 'x' by using factorization method. And to remove the bars which represent absolute value that means positive values
Required expression: |2x - 4| = 15
⇒ 2x = 15 + 4 = 19
⇒ x = 19/2 = 9.5
After factorization, the absolute value of the variable 'x' is 9.

What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
let the integer be x
then, next consecutive odd integer will be x + 2
Now, according to the question :
integer is subtracted from 2 times the next consecutive odd integeb the difference is 9 means :
2(x+2) - x = 9
2x+ 4-x = 9

Suppose the domain of f is ( -1, 1).
Define the fucnction g by g(x)=f([tex]\frac{x+1}{x-1}[/tex]).
What is the domain of g?
Answers
If the domain of f is ( -1, 1), then the function g defined by g(x) = f((x + 1)/(x - 1)) has a domain of; (-2, 0)
What is the domain of the function?The domain of a function refers to the set of all possible intput values that make the function possible.
Now, we are given the function;
g(x) = f((x + 1)/(x - 1))
The domain would be a set of real numbers excluding 1 because at x = 1, the function is undefined.
Since the domain of f(x) is -1 < x < 1 ,
Then the domain of f(x + 1) is -1 < x + 1 < 1 .
domain of -1 < x + 1 < 1 will simplify to -2 < x < 0
Thus, we can say that the domain of f(x + 1) is (-2, 0).
Thus;
g(x) = f(x + 1) and as such, the domain of g(x) is (-2, 0) .

Under certain conditions the pressure of a gas varies directly with the temperature. When the - pressure is 800 psi, the temperature is 400°. What is the temperature when the pressure is 450
Answers
The temperature when the pressure is 450 is 225°.
What is Direct Variation?In the case of an increase or decrease in both quantities by the same factor, two quantities are said to follow a direct variation. As a result, when one quantity rises, the other follows suit, and vice versa when one quantity falls. In other words, if the ratio of the first quantity to the second quantity is a constant term, the quantities are said to be directly proportional to one another. The term "coefficient or constant of proportionality" refers to this constant number.Given:
The pressure of a gas varies directly with the temperature.
So, P ∝ T
P = kT , here k is the constant of proportionality
Pressure(P) = 800psi
Temperature(T) = 400°
Putting the values to get the value of k,
P = kT
800 = 400k
k = 2
We need to find the temperature when the pressure is 450.
P = kT
450 = 2T
T = 450/2
T = 225°
Therefore, the required temperature is 225°.

Dilation rule: Do,k
Point = (9, 6)
Image = (3, 2)
As a general rule of dilation, the following are the properties of a scaled copy of another figure
If the scale factor is greater than 1, the side lengths would be greater than the original figureIf the scale factor is less than 1, the side lengths would be less than the original figureThe side lengths may or may not be whole numbersUsing the above as a guide, the scaled factor is calculated as
Scaled factor = Image/Poins

[tex]\implies y-11=-\dfrac{4}{3}x-\dfrac{28}{3}[/tex]
[tex]\implies y-11+11=-\dfrac{4}{3}x-\dfrac{28}{3}+11[/tex]

To write the equation in standard form, eliminate the fraction, bring the terms in x and y to the left of the equation, and the constants to the right:
[tex]\implies y-11=-\dfrac{4}{3}(x+7)[/tex]
[tex]\implies (y-11) \cdot 3=-\dfrac{4}{3}(x+7) \cdot 3[/tex]

mutual fund to maximize the return? What is the maximum return?
Answers
What is inequality?
Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Let x be the investment in CD
Let y be in mutual fund
Given;
Return = 6% x + 8% y
Return = 0.06 x + 0.08 y
The equation form;
we have a critical number as
(16000, 8000) :
return = 0.06 (16000 + 0.08 (8000) = $1600
(50000, 25000) :
return = 0.06 (50000) + 0.08 (25000) = $5000
(67000, 8000)
return = 0.06 (67000) + 0.08(8000) = $4660
As we can see the maximum benefit is $5000 so;
The investment in cd = x = $50000
The investment in mutual funds = $ 25000
The maximum return = $5000
