Simplifying the algebraic expression [tex]( x + 4 ) ( 2 x + 9 )[/tex] will give an answer [tex]2x^{2}+17x+36[/tex].
The technique of writing an algebraic expression in the most effective and compact form without altering the original expression's value is known as simplification.
The procedure involves gathering related phrases, which calls for adding or removing terms from an expression.
According to the distributive property of algebraic expressions, each term in an expression's sum or difference must be multiplied by a number outside of the parenthesis. A number is used as the value outside of the parenthesis with the total or difference.
Here the algebraic expression is:
[tex]( x + 4 ) ( 2 x + 9 )[/tex]
Use the distributive property to simplify the expression,
⇒ [tex]( x + 4 ) ( 2 x + 9 )[/tex]
⇒ [tex](x)(2x)+(x)(9)+(4)(2x)+(4)(9)[/tex]
⇒ [tex]2x^{2} +9x+8x+36[/tex]
⇒ [tex]2x^{2} +17x+36[/tex]
Therefore, the solution will be [tex]2x^{2} +17x+36[/tex] when the algebraic expression is simplified.

in the simplex method, the pivot column is the column with the most negative number (to the left of the vertical bar) in the bottom row. why?
The most negative number corresponds to the variable that has the largest impact on the Value of the objective function. So, maximizing it first is most efficient.
What is pivot column in simplex method?
The Simplex method's pivot column is selected by the fundamental variable's biggest reduced cost coefficient. 4. The highest ratio of right side parameters to positive coefficients in the pivot column determines the pivot row in the Simplex approach.
A location of a leading entry in the matrix's echelon structure. A pivot is a non-zero number that is either transformed into a leading 1 and then used to make 0s, or it is utilized in a pivot position to create 0s.

Kayden's math teacher said that each

score on the test.
Step-by-step explanation:
Kayden's math teacher said that each question answered correctly on a test would be worth 7 points. Answer the questions below regarding the relationship between the number of questions correct and the score on the test.
Since 00 questions correct gets you 00 points on the test, the function will have a yy-intercept of 0.0.
The rate at which points are earned is 7 points per question, so the slope of the function should be 7.7.
\text{Function Rule:}
Function Rule:
V(x)=7x
V(x)=7x
Plug x=11 Into Rule:
V(11)=7(11)=77
Correct Answer:
The independent variable, x, represents the number of questions correct, and the dependent variable is the score on the test, because the score on the test depends on the number of questions correct.
A function relating these variables is V(x) =V(x)= 7x7x.
So V(11) =V(11)= 7777, meaning 1111 questions correct will earn 7777 points on the test

Step-by-step explanation:
(7 × 10) + (7 × 10%) + (7 × 10²) = 700 070.07
Write down a possible set of values for x, y and z.
The equation (7 × 10) + (7 × 10%) + (7 × 10²) = 700 070.07 can be rewritten as:
7x + 0.7y + z = 700 070.07
To find a set of values for x, y, and z that satisfies this equation, we can use trial and error. One possible set of values is:
x = 100
y = 10
z = 7000
If we plug these values into the equation, we get:
(7 × 100) + (7 × 0.1) + (7 × 7000) = 700 070.07
Which simplifies to:
700 + 0.7 + 49000 = 700 070.07
This equation is true, so the values x = 100, y = 10, and z = 7000 are a solution to the original equation.

what is the slope of the line tangent to f(x)= x-sin(x) at x= pi
The slope of the line tangent to the given function would be m= 2.
What is the slope of the function?
If the function f(x) is given then differentiation will give you the gradient or slope for the tangent at any point.
The given function is f(x) = x - sinx
Now differentiating the above function with respect to x.
f'(x) = 1 - cosx
Now put x = π, we get
Slope = 1 - cos(π)
= 1 - (-1)
= 1 + 1
Slope (m) = 2.
Hence, the slope of the line tangent to the given function would be m= 2.

Multiple choice:
-$4.62
-$1.00
$1.00
$4.62
Answer:
Hope this helps, Good Luck! :)
Step-by-step explanation:
EV = - + prob(win)*win
= -5 + 1/1000 * 375
= -4.62
The requried, the expected value for a person that buys one ticket is approximately -$4.62. The correct answer is option A. -$4.62.
To calculate the expected value, we need to consider the probability of winning the color television and the corresponding value of the prize. We can then subtract the cost of buying the ticket to find the expected value.
Given:
Cost of one ticket = $5
Value of the color television (prize) = $375
Number of tickets sold = 1000
The probability of winning the color television is 1 out of 1000, as only one ticket will be selected out of the total 1000 tickets sold.
Expected Value (EV) = (Probability of winning * Value of prize) - Cost of the ticket
EV = (1/1000 * $375) - $5
EV = $0.375 - $5
EV = -$4.625
Rounded to two decimal places, the expected value for a person that buys one ticket is approximately -$4.62. The correct answer is option A. -$4.62.
