Answer:
[tex] x = 45 \ \& \ y = 5 [/tex]
Step-by-step explanation:
The system of linear equations in two variables is ,
[tex]\begin{cases} x = 9y \cdots (i)\\ x - 5y = 20\cdots (ii) \end{cases}[/tex]
We can easily solve out this Question using substitution method . For that , substituting x = 9y from equation (i) to equation (ii) , we have ,
[tex]\implies x - 5y = 20 \\\\\implies 9y - 5y = 20 \\\\\implies 4y = 20 \\\\\implies y =\dfrac{20}{4}\\\\\implies\boxed{\boxed{ y = 5 }}[/tex]
Substituting this value in (i) ,
[tex]\implies x = 9y \\\\\implies x = 9\times 5 \\\\\implies \boxed{\boxed{ x = 45 }}[/tex]
Answer: (45,5)
Step-by-step explanation:
You're given what x equals: 9y. Substitute that into the equation x - 5y = 20. Your equation should look like this: 9y - 5y = 20. From there, solve for y. 9y subtracted by 5y is 4y. Then, solve 4y = 20. Divide both sides of the equation by 4. The result is y = 5. We now know the y-coordinate in the ordered pair. Substitute this y-value into the first equation: x = 9y. 9(5) = 45. x = 45.
Plug these two values into the ordered pair (x,y).

Listed in the Item Bank are key terms and expressions, each of which is associated with one of the columns. Some terms may display additional information when you click on them. Drag and drop each item into the correct column. Order does not matter.
Item Bank: Blue graph | Green graph | Red graph | Table 1 | Table 2 | Table 3
Linear | Non-Linear
Answer:
Non-linear: red graph, table 3, table 1
Linear: blue graph, green graph, table 2
Step-by-step explanation:
The blue and green lines are straight lines, so they are linear. The red line is curved, so that is nonlinear.
I plotted out the data from each table on a graph. Tables 1 and 3 both curve when the points are connected, and table 2’s points form a straight line when connected. I am sure there is a mathematical formula to use on these tables, so the drawing wouldn’t have been required. But I knew this would at least get the answers.

The following data points represent the number of quesadillas each person at Tobys tacos ate, HELP
Answer: 1
Step-by-step explanation:
First order from least to greatest find the median wich would be 1 then slpit then split the numbers beyond the right side of 1 and split the split the numbers of the right aside of one. You should have 5 numbers on each side ( rember don’t include median) next find the median of both sides for the left it’s 1/4 and for the right it’s 5/4 subtract them to get 4/4 or the answer 1.
Answer:
Part 1: 0, 0, 1/4, 1/2, 1/2, 1, 1, 1, 5/4, 2, 2.
Part 2: 1 quesadilla.
Step-by-step explanation:
Part 1: The data points given are 0, 0, 1/4, 1/2, 1/2, 1, 1, 1, 5/4, 2, and 2.
The data are already sorted from least to greatest.
Part 2: To get the interquartile range, we must know the first and third quartiles. To find those, we need to know the median of the data.
There are 11 data points, so we can cross out 5 numbers on the left and cross out 5 numbers on the right. That leaves a median of 1.
Since we know the median is 1, we can find the first quartile by finding the median of the following numbers: 0, 0, 1/4, 1/2, 1/2 (any number less than 1). There are five numbers, so cross out two numbers from the left and cross out two numbers from the right. We are left with a first quartile of 1/4.
Now that we have the first quartile, we need to find the third quartile. Since the median was actually the first "1" in the data set, the third quartile will be the median of the numbers to the right of that "1": 1, 1, 5/4, 2, 2. Cross out the leftmost two numbers, and cross out the rightmost two numbers. We are left with a third quartile of 5/4.
Now that we have both the third and first quartiles, we can find the interquartile range! The IQR is calculated by finding the third quartile minus the first quartile. 5/4 - 1/4 = 4/4 = 1.
So, your interquartile range is 1 quesadilla.
Hope this helps!
Suppose you'd like to save enough money to pay cash for your next car. The goal is to save an extra $26,000 over the next 3 years. What amount must be deposited
quarterly into an account that earns 4.4% interest in order to reach your goal? Round your answer to the nearest cent, if necessary.
you would have to deposit approximately $22,807 quarterly into the account to reach your goal of saving $26,000 over the next 3 years at an interest rate of 4.4%.
Use the concept of compound interest defined as:
The interest that is computed using both the principal and the interest that has accrued during the previous period is called compound interest.
The compound interest formula is:
[tex]A = P(1 + r/n)^{(nt)}[/tex]
Where,
A is compounded amount
P is the principal amount
r is the rate of interest
n is the number of times compounding
t is time.
Given that,
Goal: Save enough money to pay cash for the next car.
Target amount: $26,000.
Timeframe: Over the next 3 years.
Interest rate: 4.4%.
Deposit frequency: Quarterly.
To calculate the amount you need to deposit quarterly to reach $26,000 over the next 3 years with an interest rate of 4.4%,
Use the formula of compound interest described above:
Where,
A = $26000
P =?
r = 4.4% or 0.044 as a decimal
n = 4
t = 3 years
Substituting the given values, we get:
[tex]26,000 = P(1 + 0.044/4)^{4\times3}[/tex]
Simplifying further:
[tex]26,000 = P(1 + 0.011)^{12 }[/tex]
[tex]26,000 = P(1.011)^{12}\\\\26,000 = P(1.1402)[/tex]
To solve for P, divide both sides of the equation by 1.1402:
P = 26,000 / 1.1402
P ≈ 22,807
Hence, you would have to deposit approximately $22,807 quarterly into the account.

Answer:
I think it is x=1/1024 not sure but try it
Answer:
x = - [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Assuming you mean
[tex]16^{x}[/tex] = [tex]\frac{1}{64}[/tex]
note that 16 = 4² and 64 = 4³ , so
[tex](4^{2} )^{x}[/tex] = [tex]\frac{1}{4^{3} }[/tex]
[tex]4^{2x}[/tex] = [tex]4^{-3}[/tex]
Since the bases on both sides are equal, both 4, then equate exponents
2x = - 3 ( divide both sides by 2 )
x = - [tex]\frac{3}{2}[/tex] ( = - 1.5 )
A circle is drawn inside a square so its circumference touches each of the four sides of the square. If the area of the circle is 99.2cm2 calculate the length of the sides of the square.
Answer:
The length of the sides of the square is approximately 11.239 centimeters.
Step-by-step explanation:
Since the circle is inscribed in the square, the length of each side of the square ([tex]l[/tex]), in centimeters, is equal to the length of the diameter of the circle ([tex]D[/tex]), in centimeters. The area of the circle ([tex]A_{c}[/tex]), in square centimeters:
[tex]A_{c} = \frac{\pi\cdot D^{2}}{4}[/tex] (1)
Where [tex]D[/tex] is the diameter of the circle, in centimeters.
If we know that [tex]A_{c} = 99.2\,cm^{2}[/tex], then the length of the sides of the square is:
[tex]D = \sqrt{\frac{4\cdot A_{c}}{\pi} }[/tex]
[tex]l = D \approx 11.239\,cm[/tex]
The length of the sides of the square is approximately 11.239 centimeters.
Int sin(x+a)/sinx dx
Answer:
[tex] \displaystyle \rm x \cos(a) + \sin(a) \ln\left( | \sin(x) | \right) + C[/tex]
Step-by-step explanation:
we would like to integrate the following integration:
[tex] \displaystyle \int \frac{ \sin(x + a) }{ \sin(x) } dx[/tex]
we can rewrite the denominator by using algebraic identity given by:
[tex] \displaystyle \rm\sin( \alpha \pm \beta ) = \sin( \alpha ) \cos( \beta ) \pm \cos( \alpha ) \sin( \beta ) [/tex]
thus substitute:
[tex] \displaystyle \int \frac{ \sin(x ) \cos(a) + \cos(x) \sin(a) } { \sin(x) } dx[/tex]
we should rewrite integrand as sum therefore we can use sum integration formula
[tex] \displaystyle \rm\int \frac{ \sin(x ) \cos(a) } { \sin(x) } + \frac{ \cos(x) \sin( \alpha ) } { \sin(x) } dx[/tex]
use sum integration formula:
[tex] \displaystyle \rm\int \frac{ \sin(x ) \cos(a) } { \sin(x) } dx + \int \frac{ \cos(x) \sin( \alpha ) } { \sin(x) } dx[/tex]
reduce fraction:
[tex] \displaystyle \rm\int \cos(a) dx + \int \frac{ \cos(x) \sin( \alpha ) } { \sin(x) } dx[/tex]
rewrite:
[tex] \displaystyle \rm\int \cos(a) dx + \int \frac{ \cos(x) } { \sin(x) } \cdot \sin( a) dx[/tex]
use trigonometric indentity:
[tex] \displaystyle \rm\int \cos(a) dx + \int \cot(x) \cdot \sin( a) dx[/tex]
use constant integration formula
[tex] \displaystyle \rm\int \cos(a) dx + \sin(a) \int \cot(x) dx[/tex]
use integration rules:
[tex] \displaystyle \rm x \cos(a) + \sin(a) \ln\left( | \sin(x) | \right)[/tex]
and finally we of course have to add constant of integration
[tex] \displaystyle \rm x \cos(a) + \sin(a) \ln\left( | \sin(x) | \right) + C[/tex]
And we are done!

Find the ordered pair that is a member of both -2x + 6y = 34 and
2x + 2y = 14 or indicate if it does not exist or there are infinite
possibilities.
Answer:
(1, 6) is the solution
Step-by-step explanation:
-2x + 6y = 34
2x + 2y = 14; divide by 2
x + y = 7; subtract x
y = 7 - x
let's substitute y with 7 - x in first equation
-2x + 6*(7 - x) = 34; expand multiplication
-2x + 6*7 - 6*x = 34; group
-8x + 42 = 34; subtract 42
-8x = 34 - 42 = -8; divide by -8
x = 1
y = 7 - 1 = 6
It is the only solution, as we've arrived at exact numbers.

A rectangular field has a perimeter of 100 feet. Its length is 20 feet longer than its width.
What are the dimensions of the field?
O A. 15 feet by 35 feet
O B. 20 feet by 30 feet
O c. 35 feet by 55 feet
O
D. 40 feet by 60 feet
Answer:
A. 15 feet by 35.
Step-by-step explanation:
According to this word problem, the rectangular field has a perimeter of 100 feet.
The formula for perimeter of a rectangle is side + side + side + side.
A rectangle has two pairs of equal sides and four sides.
So, the equation to represent the perimeter would be:
15 + 35 + 15 + 35 = 100.
Now, we must answer the second part of the question.
"The length is 20 feet longer than its width."
The width is 15.
15 + 20 = 35.
35 is twenty feet longer than 15.
Therefore, the dimensions of the field are 15 feet by 35 feet.
