An equation is a group of numerical variables and functions that have been combined using operations like addition, subtraction, multiplication, and division.
Given that,
Kylie earns a $15 commission for every phone she sells and a $2 commission for every accessory she sells.
And, On a given day, Kylie made a total of $352 in commission and sold 6 more accessories than phones.
Let us assume that,
The number of phones sold = x
And, the number of accessories sold = y
Hence, the equation becomes,
15x + 2y = 352 .. (i)
And, y = x + 6 .. (ii)
Substitute the value of y in (i);
15x + 2y = 352
15x + 2 (x + 6) = 352
15x + 2x + 12 = 352
17x + 12 = 352
17x = 352 - 12
17x = 340
x = 340/17
x = 20
From (ii);
y = x + 6
y = 20 + 6
y = 26
Therefore, The number of phones sold = 20
And, the number of accessories sold = 26

An inductive proof that p(n) is true for all n always starts with the base case. what is the base case?
The base case for which the inductive proof for p(n) is defined, is the smallest value of n for which p(n) is defined.
What is Mathematical Induction?Mathematical induction refers to a strategy for demonstrating a theorem's correctness by first demonstrating that, if it holds true in one particular situation, it will also hold true in all subsequent cases in the series.
Now,
The proof of mathematical induction is based upon showing the given expression true for one value, assuming that it will be true for some other value and finally proving that it will be true for all the values.The base case is the proof for which the expression is showed to be true in the beginning.In general cases, this initial value is 1 when the expression is defined for the values of variables belonging to Natural Numbers, i.e., the proof starts by showing that the given expression is true for the value of variable = 1.Hence, the base case for which the inductive proof for p(n) is defined, is the smallest value of n for which p(n) is defined.

why are marcel’s and stephanie’s taxable incomes less than their annual salaries?
The taxable income of Marcel and Stephanie is less than their annual salary because they are allowed to make deductions from their income before calculating their taxable income.
These deductions include contributions to retirement plans, health insurance premiums, and other eligible expenses. The amount of deductions varies depending on factors such as the type of expense and the individual's tax filing status.
Thus, the taxable income is the amount of income that is subject to taxation, and it is generally lower than the individual's annual salary. In the case of Marcel and Stephanie, their taxable incomes are calculated by subtracting their deductions from their respective annual salaries.

Step-by-step explanation:
If Sara wanted her total amount paid to be even lower ,what could she do?
If Sarah wanted her total payments to be even lower, then she can either choose a different plan or increase the amount she is paying every month.
How should Sarah ensure that total amount paid is even lower?Usually, income-based repayment plans are typically used by people who do not make a lot of money and would prefer to pay smaller debt repayment installments. These plans will limit her monthly payments to 10% - 20% of her income.
The problem with these is that the debt will take longer to pay off with lower monthly/periodic payments. This will allow interest to accumulate on the debt for a longer period of time, resulting in her paying more than she would have if she had not used income-based repayment plans. However, if she want her total payments to be even lower, then she can either choose a different plan or increase the amount she is paying every month.
Missing words "Sarah looks at these results and realizes her monthly payment would be lower with most of the income-based repayment plans. But then, she looks at the Total Amount Paid and realizes that the loan price increases when she chooses these plans."

The International Air Transport Association surveys business travelers to develop quality ratings for transatlantic gateway airports. The maximum possible rating is 10. Suppose a simple random sample of 50 business travelers is selected and each traveler is asked to provide a rating for the Miami International Airport. The ratings obtained from the sample of 50 business travelers follow.
7 7 3 8 4 4 4 5 5 5 5 4 9
10 9 9 8 10 4 5 4 10 10 10 11 4

Develop a 95% confidence interval estimate of the population mean rating for Miami. Round your answers to two decimal places.
The 95% confidence interval estimate of the population mean rating for Miami International Airport is approximately 5.50 to 6.74 (rounded to two decimal places).
To develop a 95% confidence interval estimate of the population mean rating for Miami International Airport, we can use the sample data provided. Here are the steps to calculate the confidence interval:
Step 1: Calculate the sample mean and sample standard deviation (s) from the given ratings.
Step 2: Determine the critical value (t*) for a 95% confidence level. Since the sample size is small (n = 50), we need to use the t-distribution. The degrees of freedom (df) will be n - 1 = 50 - 1 = 49.
Step 3: Calculate the standard error (SE) using the formula: SE = s / √n, where n is the sample size.
Step 4: Calculate the margin of error (ME) using the formula: ME = t* * SE.
Let's proceed with the calculations:
Step 1: Calculate the sample mean and sample standard deviation (s).
Sample ratings: 7 7 3 8 4 4 4 5 5 5 5 4 9 10 9 9 8 10 4 5 4 10 10 10 11 4 9 7 5 4 4 5 5 4 3 10 10 4 4 8 7 7 4 9 5 9 4 4 4 4
Sample size (n) = 50
Sample mean = (Sum of ratings) / n = (306) / 50 = 6.12
Sample standard deviation (s) = 2.18
Step 2: Determine the critical value (t*) for a 95% confidence level.
Using a t-distribution with 49 degrees of freedom and a 95% confidence level, the critical value (t*) is approximately 2.01.
Step 3: Calculate the standard error (SE).
SE = s / √n = 2.18 / √50 ≈ 0.308
Step 4: Calculate the margin of error (ME).
ME = t* * SE = 2.01 * 0.308 ≈ 0.619
Step 5: Construct the confidence interval.
Confidence Interval = 6.12 ± 0.619
Lower bound = 6.12 - 0.619 ≈ 5.501
Upper bound = 6.12 + 0.619 ≈ 6.739
The 95% confidence interval estimate of the population mean rating for Miami International Airport is approximately 5.50 to 6.74 (rounded to two decimal places).

f(x)=5sinx+cosx then f ′
(x)=−5cosx−sinx Select one: True False
False. The derivative of the function f(x) = 5sin(x) + cos(x) is not equal to -5cos(x) - sin(x). The correct derivative of f(x) can be obtained by applying the rules of differentiation.
To find the derivative, we differentiate each term separately. The derivative of 5sin(x) is obtained using the chain rule, which states that the derivative of sin(u) is cos(u) multiplied by the derivative of u. In this case, u = x, so the derivative of 5sin(x) is 5cos(x).
Similarly, the derivative of cos(x) is obtained as -sin(x) using the chain rule.
Therefore, the derivative of f(x) = 5sin(x) + cos(x) is:
f'(x) = 5cos(x) - sin(x).
This result shows that the derivative of f(x) is not equal to -5cos(x) - sin(x).
In summary, the statement that f'(x) = -5cos(x) - sin(x) is false. The correct derivative of f(x) = 5sin(x) + cos(x) is f'(x) = 5cos(x) - sin(x).

Study the following figure, where two concentric circles share center C.
Segment AB is a diameter of the larger circle.
Segment AB intersects a chord of the smaller circle, PQ, at a right angle at point Z.
Segment AB intersects a chord of the larger circle, MN, at a right angle at point 0.
If MO=7x-4, and NO=6x, what is the length of MN
Answer:
Length of MN = 48 units
Step-by-step explanation:
AB is the diameter of the larger circle which is perpendicular to both the chords PQ (chord of the smaller circle) and MN(chord of the larger circle).
Theorem says,
"Radius or a diameter of a circle which is perpendicular to the chord divides the chord in two equal parts."
Therefore, MO ≅ ON
m(MO) = m(ON)
7x - 4 = 6x
7x - 6x = 4
x = 4
m(MN) = m(MO) + m(ON)
= (7x - 4) + (6x)
= 13x - 4
= (13 × 4) - 4
= 52 - 4
= 48
Length of chord MN will be 48 units.
What are the coordinates of polygon JKLM with the vertices at J(-1,4), K(2,5), L(5,2), and M(4,-1) after it is reflected over the y=x?
Answer:
The polygons will have its vertices after a reflection over the y=x will be:
J'(4, -1)K'(5, 2)L'(2, 5)M'(-1, 4)Step-by-step explanation:
We know that when we reflect a point across the line y = x, the x-coordinate, and y-coordinate tend to replace their places.
i.e.
The reflection of the point (x,y) across the line y = x is the point (y, x).
P(x, y) = P'(y, x)
Given the points before the a refecltion over y=x
J(-1, 4)K(2, 5)L(5, 2)M(4, -1)Thus, the coordinates after the polygon are reflected over the y=x will be:
P(x, y) = P'(y, x)
J(-1, 4) = J'(4, -1)
K(2, 5) = K'(5, 2)
L(5, 2) = L'(2, 5)
M(4, -1) = M'(-1, 4)
Therefore, the polygons will have its vertices after a reflection over the y=x will be:
J'(4, -1)K'(5, 2)L'(2, 5)M'(-1, 4)given f(x) = -x -4 find f (-2)

solve the given differential equation. 7xy'' 7y' = 0
the general solution of the given differential equation is: y = C7 + C8/x.
The differential equation 7xy'' + 7y' = 0 can be solved as follows: 7xy'' + 7y' = 0
The given differential equation is a second-order linear differential equation of the form y'' + f(x) y' + g(x) y = 0, where f(x) = 7/x and g(x) = 0.
On dividing both sides by 7x, we get:y''/x + y'/x = 0
Now, substituting p = y'/x, we get:y''/x = dp/dx + p/x
Hence, the given differential equation can be written as:dp/dx + p/x = 0
This is a first-order linear differential equation of the form dy/dx + P(x) y = Q(x), where P(x) = 1/x and Q(x) = 0.
Now, multiplying both sides by the integrating factor I(x) = e^∫P(x)dx = e^∫(1/x)dx = e^lnx = x, we get:x dp/dx + p = 0
Multiplying both sides by dx and integrating, we get:∫x dp/p = -∫dxln |p| = -ln |p| + C1x ln |p| = C2
Taking antilogarithm on both sides, we get:|p| = e^(C2/x)Multiplying both sides by a constant of integration C3, we get:
p = ± C3 e^(C2/x)But p = y'/xHence, y'/x = ± C3 e^(C2/x)
Integrating both sides with respect to x, we get:y = C4 + C5 ∫e^(C2/x) dxwhere C4 and C5 are constants of integration.
Using the substitution t = C2/x, we get:dy/dt = - C5/t²Hence, y = C4 - C5 ∫dt/t²= C4 + C5/t + C6 where C6 is a constant of integration.
Substituting t = C2/x, we get:y = C4 + C5 C2/x + C6x= C7 + C8/x where C7 and C8 are constants of integration.
Hence, the general solution of the given differential equation is: y = C7 + C8/x.

Find a formula for the exponential function passing through the points (-3,1/2) and (3,32).
The exponential function passing through the points (-3, 1/2) and (3, 32) can be represented by the equation \(f(x) = (2^{(5/6)}) * (2^{(x/6)})\).
To find the exponential function passing through the given points, we can start by assuming the general form of an exponential function, \(f(x) = a * (b^x)\), where a and b are constants to be determined. Plugging in the coordinates (-3, 1/2) into this equation gives us \(1/2 = a * (b^{(-3)})\), and plugging in (3, 32) gives us \(32 = a * (b^3)\).
Now, we can solve this system of equations to find the values of a and b. Taking the ratio of the two equations, we get \((1/2) / 32 = (a * (b^{(-3)})) / (a * (b^3))\), which simplifies to \(1/64 = 1/b^6\). Solving for b, we find \(b = 2^{(1/6)\).
Substituting this value back into either of the original equations, we can solve for a. Using the equation \(1/2 = a * (2^{(-3/6)})\), we find \(a = 2^{(5/6)\).
Therefore, the exponential function passing through the given points is \(f(x) = (2^{(5/6)}) * (2^{(x/6)})\).

True/False? To calculate the total number of iterations of a nested loop, add the number of iterations of all the loops
In order to calculate the total number of iterations of a nested loop, you need to add the number of iterations of all the loops. This is because the iterations of each loop are cumulative and dependent on each other. Therefore, adding the number of iterations of all the loops will give you the total number of iterations of the nested loop.
In a nested loop, the inner loop will always complete its iteration each time the outer loop runs once. Thus, the total number of iterations of a nested loop is the sum of the iterations of all the loops. For example, if the outer loop has 5 iterations and the inner loop has 3 iterations, then the total number of iterations of the nested loop would be 5 x 3 = 15. Similarly, if there are more than two loops nested together, the total number of iterations of the nested loop would be the sum of the iterations of all the loops.

the remaining money to buy new cycling outfits for $78.12 each. Write and
solve an inequality to determine the greatest number of cycling outfits
that Mr. Mc Donald can buy with the remaining money? *
Answer:
This will explain it
Step-by-step explanation:
To answer the question, you need to determine the amount Mr. Traeger has left to spend, then find the maximum number of outfits that will cost less than that remaining amount.
Spent so far:
... 273.98 + 3×7.23 +42.36 = 338.03
Remaining available funds:
... 500.00 -338.03 = 161.97
The cycling outfits are about $80 (slightly less), and this amount is about $160 (slightly more), which is 2 × $80.
Mr. Traeger can buy two (2) cycling outfits with the remaining money.
_____
The remaining money is 161.97/78.12 = 2.0733 times the cost of a cycling outfit. We're sure he has no interest in purchasing a fraction of an outfit, so he can afford to buy 2 outfits.
