This refers to the tax paid to a governing body for the sales of certain goods and services.
In Williamson County, the sales tax rate is 9.75% = 9.75% × $1,000 = $1,097.5
In Davidson County , the sales tax rate is 9.25% = 9.25% × $1,000 = $1,092.5
The amount saved will therefore be $1,097.5 - $1,092.5 = $5.

Define a polynomial that is a difference of squares. How do you know that it is the difference of squares? How is it factored?
Answer:
When an expression can be viewed as the difference of two perfect squares, i.e. a²-b², then we can factor it as (a+b)(a-b). For example, x²-25 can be factored as (x+5)(x-5). This method is based on the pattern (a+b)(a-b)=a²-b², which can be verified by expanding the parentheses in (a+b)(a-b).
Step-by-step explanation:

x^2-x-2=0 as a complete square
Answer:
[tex]x_1=2; x_2=-1[/tex]
Step-by-step explanation:
The square term is [tex]x^2[/tex] so we expect the complete square to be of the form [tex](x-a) ^2=x^2+2ax+a^2[/tex].
Let's compare the first degree terms now: we have [tex]2ax[/tex] on one side and [tex]-1x[/tex] on the other. That would make [tex]a=- \frac12[/tex]. At this point we have still the second squared term, so we add and subtract [tex]\frac14 = (\frac12)^2[/tex]
Our equation becomes:
[tex]x^2-x+\frac14 -\frac14-2 =0\\(x-\frac12)^2-\frac94=0[/tex]
(the [tex]\frac94[/tex] term comes from rewriting [tex]2= \frac84[/tex] and adding the terms out of the bracket).
At this point it's just solving the equation:
[tex](x-\frac12)^2 = \frac94 \rightarrow x-\frac12=\pm\frac32\\x=\frac12\pm\frac32\\x_1=\frac42 = 2; x_2=\fra-\frac22=-1[/tex]

Step-by-step explanation:
Solve for x
7x – 1= 2x + 3
Give your answer as a fraction in its simplest form.
Answer:
x = 4/5.
Step-by-step explanation:
7x - 1 = 2x + 3
Move one to the other side.
7x = 2x + 4
Subtract the 2x to the other side
5x = 4
Divide both sides by 5
x = 4/5.
Answer:
x = 0.8
Step-by-step explanation:
To find x, we need to isolate the constants on one side and the variables on the other. Simply subtract 2x both sides and add 1 both sides.
⇒ [tex]7x - 1= 2x + 3[/tex]
⇒ [tex]7x - 1 - 2x + 1 = 2x + 3 + 1 - 2x[/tex]
⇒ [tex]5x = 2x + 3 + 1 - 2x[/tex]
⇒ [tex]5x = 3 + 1[/tex]
Now, simplify the RHS.
⇒ [tex]5x = 3 + 1[/tex]
⇒ [tex]5x = 4[/tex]
Finally, divide 5 both sides to isolate the x variable.
⇒ [tex]\frac{5x}{5} = \frac{4}{5}[/tex]
⇒ [tex]x = \frac{4}{5} = 0.8[/tex]

What is the distance between two points?The length of the line segment bridging two points on a plane is known as the distance between the points.
The formula to find the distance between the two points is usually given by d=√{(x₂-x₁)² + (y₂-y₁)²}
Given:
The three points P(1,2), Q(16,10), and R(22,2) are on the coordinate plane.
To find the lengths of the different line segments in the given figure, we can use the distance formula:
Distance = √[(x2 - x1)² + (y2 - y1)²]
(A) To find the length of QS, we need to find the difference between the y-coordinates of Q and S:
QS = |10 - 2| = 8
Therefore, QS has a length of 8 units.
(B) To find the length of PS, we need to find the difference between the x-coordinates of P and S:
PS = |16 - 1| = 15
Therefore, PS has a length of 15 units.
(C) To find the length of SR, we need to find the difference between the x-coordinates of S and R:
SR = |22 - 16| = 6
Therefore, SR has a length of 6 units.
(D) To find the length of PQ, we need to find the difference between the x-coordinates of P and Q:
PQ = √[1 - 16)² + (2 - 10)²]
Therefore, PQ has a length of 17 units.
(E) To find the length of QR, we need to use the distance formula:
QR = √[(22 - 16)² + (2 - 10)²]
= √[36 + 64]
= √100
= 10
Therefore, QR has a length of 10 units.

A consumer agency wants to determine which of two laundry detergents, A or B, cleans better. Fifty 1-square-foot sections of fabric are randomly selected and cut from different bolts of fabric. They are then subjected to the same kinds of stains (grass, mud, coffee). Then 25 pieces are randomly assigned to be cleaned with detergent A, and the remaining 25 pieces are cleaned with detergent B. After being laundered, the pieces of fabric are rated on a scale of 1–10, with 1 being the least clean to 10 being the most clean. The mean rating for detergent A is found to be significantly greater than the mean rating for detergent B.
Which of the following is a valid conclusion?
Inferences can be made about the population of fabric from which the pieces were cut. The conclusion can be made that detergent A cleans better than detergent B for the fabric from these bolts.

An arithmetic sequence has this recursive formula:
|a =7
n = an=1
- 4
What is the explicit formula for this sequence?
An arithmetic sequence can be expressed as explicitly or recursively
The explicit formula of the sequence is [tex]a_n = 11 - 4n[/tex]
How to determine the explicit formulaThe recursive formula is given as:
[tex]a_n = a_{n -1} - 4[/tex]
[tex]a_1 = 7[/tex]
Substitute 2 for n in [tex]a_n = a_{n -1} - 4[/tex]
[tex]a_2 =a_1 - 4[/tex]
This gives
[tex]a_2 =7 - 4[/tex]
[tex]a_2 =3[/tex]
Calculate the common difference (d)
[tex]d = a_2 -a_1[/tex]
[tex]d = 3- 7[/tex]
[tex]d = -4[/tex]
The explicit formula is then calculated as:
[tex]a_n = a_1 + (n - 1)d[/tex]
This gives
[tex]a_n = 7+ (n - 1)*-4[/tex]
Expand
[tex]a_n = 7+4 - 4n[/tex]
[tex]a_n = 11 - 4n[/tex]
Hence, the explicit formula of the sequence is [tex]a_n = 11 - 4n[/tex]
