SOLUTION
We want to solve for x in the equation
[tex]14x-\frac{1}{2}\mleft(4x+6\mright)=3\mleft(x-4\mright)-18[/tex]First we expand the brackets in both sides of the equation, this becomes
[tex]\begin{gathered} 14x-\frac{1}{2}(4x+6)=3(x-4)-18 \\ 14x-2x-3=3x-12-18 \end{gathered}[/tex]Note that the minus sign multiplies the items in the brackets too
Now, we collect like terms we have
[tex]\begin{gathered} 14x-2x-3x=-12-18+3 \\ 9x=-27 \\ \text{divide both sides by 9, we have } \\ \frac{9x}{9}=\frac{-27}{9} \\ x=-3 \end{gathered}[/tex]Hence x = -3

Solution
Given the circle with 25 yard diameter
Circumference of a circle = 2πr
[tex]\begin{gathered} diameter\text{ =25yrd} \\ d=2r \end{gathered}[/tex]Circumference = πd
[tex]C=25\pi[/tex]Therefore the correct answer = 25pi

f(x) = x2 + 1 g(x) = 5 – x
(f + g)(x) =
x to the power of 2 – x + 6
then (f – g)(x) =??
The function operation ( f - g )( x ) in the functions f(x) = x² + 1 and g(x) = 5 - x is x² + x - 4.
What is the function operation ( f - g )( x ) in the given functions?A function is simply a relationship that maps one input to one output. Each x-value can only have one y-value.
Given the data in the question;
f(x) = x² + 1g(x) = 5 - x( f - g )( x ) = ?To find ( f - g )( x ), replace the function designators in ( f - g ) with the actual functions.
( f - g )( x ) = f( x ) - g( x )
( f - g )( x ) = ( x² + 1 ) - ( 5 - x )
Remove the parenthesis using distributive property
( f - g )( x ) = ( x² + 1 ) - ( 5 - x )
( f - g )( x ) = x² + 1 - 5 + x
Collect and add like terms
( f - g )( x ) = x² + x + 1 - 5
( f - g )( x ) = x² + x - 4
Therefore, the function operation ( f - g )( x ) is x² + x - 4.

The required function would be (f – g)(x) = x² + x - 4.
What is the function?A mathematical expression that defines the connection between two variables is considered a function.
The given functions following as
f(x) = x² + 1 and g(x) = 5 - x
We have to determine the function (f – g)(x).
(f – g)(x) = f(x) - g(x)
Substitute the values of functions f(x) = x² + 1 and g(x) = 5 - x in the function (f - g).
(f – g)(x) = (x² + 1) - (5 - x)
Open the parenthesis and apply the arithmetic operation,
(f – g)(x) = x² + 1 - 5 + x
Rearrange the terms likewise and combine them,
(f – g)(x) = x² + x + 1 - 5
Apply the subtraction operation to get
(f – g)(x) = x² + x - 4
Therefore, the required function would be (f – g)(x) = x² + x - 4.

diameter = 10.5in.we are learning something about area of circle.

Step-by-step explanation:
mark wrote this description of a quadrilateral he drew it has one pair of parallel lines and two congruent lines but the lines that are congruent are not parallel
First, draw two parallel lines:
Next, draw to additional lines of the same length that connect both parallel lines:
Notice that this can be done in two different ways. In the case in red, both lines are not parallel. In the case shown in blue, they are. Since the problem asks for the case when they are not parallel, keep in mind the figure with the lines in red. That figure is a trapezoid.

Solve the following system of equations by graphing. Graph the system below and enter the solution set as an ordered pair in the form (x,y).if there are no solutions, enter none and enter all if there are infinite solutions.X - y = 0X + y = - 4
EXPLANATION
Since we have the system of equations:
(1) x - y = 0
(2) x + y = -4
Isolating x in (1):
x = y
Plugging in x=y into (2):
y + y = -4
Adding like terms:
2y = -4
Dividing both sides by 2:
y = -4/2
Simplifying:
y = -2
Plugging in y=-2 into (1):
x - (-2) = 0
Removing the parentheses:
x + 2 = 0
Subtracting -2 to both sides:
x = -2
The solution of the system of equations is (-2, -2)

Given:
The system of equation is:

3x - 3y + 8z = -5
-6x + y + 3z = 7
Hence, the correct option is D
The following row operations are to be performed;
[tex]\begin{gathered} R_1=-2r_2+r_1 \\ \\ R_3=2r_2+r_3 \end{gathered}[/tex]The first row operation implies that you will multiply row 2 by -2 and then add to row. The resultant gives a new row 1.
This means that the elements in row 1 becomes:
Row 1 : 1 -1 - 15 | 5
Row 2: 3 -3 8 | -5
As for row 3, we will multiply row 2 by 2 and then add to row 3 to get a new row 3.

[tex]\frac{3}{8}\times54=20\frac{1}{4}[/tex]Fiona was playing a game in which she rolled two number cubes. Cube #1 had the integers 1, 2, 3, 4, 5 and 6 on its faces. Cube # 2 has the integers –1, – 2, – 3, –4, –5 and –6 on its faces. She rolled Cube # 1 and got a 2. After she rolled Cube # 2 the sum of the value on the cubes was 0. What number did she roll on Cube # 2?
When Fiona rolled Cube #2, she got a number -2 as she got 2 while rolling Cube #1 and the sum of the value on the cubes was 0.
As we know Cube #1 has integers 1, 2, 3, 4, 5, 6 on its faces and Cube #2 has -1, -2, -3, -4, -5, -6 on its faces.
It is also given that Fiona got 2 when she rolled cube #1 and the value of the sum on both the cubes is 0.
So it is clear that on Cube #2, the number must be -2 as in that case only, the sum of the values will be 0.
To prove
2 + (-1) = 1
2 + (-2) = 0
2 + (-3) = -1
Hence, the number she got on Cube #2 is -2.

paid price = 24,998
it is the amount that is 1815 less than the sticker price,

3. Express the given integral as the limit of a Riemann sum but do not evaluate:
Expression of the integral [tex]\int\limits^3_0 {(x^{3}-6x) } \, dx[/tex] as the limit of a Riemann sum without any evaluation will be
Lim(n → ∞) ∑(n = 1 → ∞) [{(27i³/n³) - (18i/n)} * (3i/n)]
As per the question statement, we are provided with an integral [tex]\int\limits^3_0 {(x^{3}-6x) } \, dx[/tex] ,
And we are required to determine the expression of the above mentioned integral as the limit of a Riemann sum without any evaluation.
To start with, we need to know the formula [Δx = {(b - a)/n}]
And here, from our given integral [tex]\int\limits^3_0 {(x^{3}-6x) } \, dx[/tex], we get that, (a = 0) and
(b = 3). Therefore substituting the values of "a" and "b" in the formula to calculate Δx, we get,
[Δx = {(3 - 0)/n} = (3/n)]
Also, [(x[tex]_{i}[/tex]) = {a + (Δx)i} = {0 + (3/n)i) = (3i/n)],
Given, [ρ(x) = (x³ - 6x)], and thus, [ρ(x[tex]_{i}[/tex]) = ρ(3i/n)]
Or, [ρ(x[tex]_{i}[/tex]) = {(3i/n)³ - 6(3i/n)}]
Or, [ρ(x[tex]_{i}[/tex]) = {(27i³/n³) - (18i/n)}]
Then, Lim(n → ∞) ∑(n = 1 → ∞) ρ(x[tex]_{i}[/tex])Δx
= Lim(n → ∞) ∑(n = 1 → ∞) [{(27i³/n³) - (18i/n)} * (3i/n)]

This model represents the amount of time Jessica takes to finish her
book. It has a width of 1 and a length of 2 1/3
. The model is 2 1/3 out of 3
Proportionately, the number of hours it takes Eric to finish the book as Jessica is 3¹/₂ hours.
What is proportion?Proportion refers to the ratio of the quantity contained in a number or value concerning another value's ratio.
Proportions, like ratios, are fractional values, represented using decimals, fractions, or percentages.
In ratio terms, Eric's reading time is 3¹/₂ hours to Jessica's 2¹/₃ hours, giving an absolute ratio of 3: 2 with a constant proportionality of 1.5 hours.
For instance, the product of Eric's reading time, compared to Jessica's reading time, shows that Jessica does a faster reading than Eric.
The total number of hours it takes Jessica to finish her book = 2¹/₃ hours
The total hours it takes Eric to finish the book = 2¹/₃ hours x 1¹/₂
= 3¹/₂ hours (2¹/₃ x 1¹/₂).
Thus, whereas Jessica takes 2¹/₃ hours to finish the book, in proportion, Eric consumes 3¹/₂ hours reading the same book.

A pottery factory purchases a continuous belt conveyor kiln for $68,000. A 6.3% APR loan with monthly payments is taken out to purchase the kiln. If the monthly payments are $765.22, over what term is this loan being paid?
Based om the cost of the continuous belt conveyor kiln and the monthly payments, as well as the APR of the loan, the term this loan will be paid is 120 months or 10 years.
How to find the term of the loan?When given the cost of a loan, the APR, and the monthly payments, you can find out the term of the loan by using the NPER function on a spreadsheet.
The Rate would be:
= 6.3% / 12 months in a year
= 0.525%
The Pmt is the payment of $765.22. This amount should be in negatives.
