Answer:
x = -3
y = -2
(-3, -2)
Step-by-step explanation:
x - 7y = 11
5x + 4y = -23

-5 (x - 7y = 11)
-5x + 35y = -55
--------------------------
-5x + 35y = -55
5x + 4y = -23

5(3x + y) when x=6 and y=2
Answer:
100
Step-by-step explanation:
If x is 6 and y is 2 the new equation would look like this: 5(3x6 + 2). 3 times 6 is 18 and add 2 is 20. Therefore you would get 20 times 5. 20x5 is 100

Step-by-step explanation:
Radius of outer circle = 6 m
Width of the track = 2 m
So, radius of inner circle = 6 - 2 = 4 m
Area of the track = Area of outer circle - Area of inner circle
\begin{gathered} = \pi {6}^{2} - \pi {4}^{2} \\ \\ = \pi( {6}^{2} - {4}^{2} ) \\ \\ = 3.14 \times (36 - 16) \\ \\ = 3.14 \times 20 \\ \\ = 62.8 \: {m}^{2} \end{gathered}

At 8 a.m. Anne left Austin and headed south at 20 mph. At 10 a.m. Gene left from the same place and headed south on the same road. If Anne was 10 miles ahead by 4 p.m. on the same day, what was Gene's speed in mph
Using proportions, it is found that Gene's speed was of 25 miles per hour, as he was 30 miles faster over a period of 6 hours.
What is a proportion?A proportion is a fraction of a total amount.
At 8 a.m. Anne left Austin and headed south at 20 mph, hence when Gene left at 10 a.m., she was 40 mph ahead.
At 4 p.m., that is, 6 hours after Gene left, the distance was of 10 miles, that is, Gene was 30 miles faster in 6 hours, so the difference in the speeds is given by:
d = 30/6 = 5 mph.
Since Anne's speed is of 20 mph, Gene's is given by:
v = 20 + 5 = 25 mph.

Answer:
Choice A
Step-by-step explanation:
End of the question states it, and I did it on Khan :)
Kara finds that the top 200200200 longest streaks in the world in June had an average of about 636363 so option (A) will be correct.
What is mean?The mean is the average of a data set. Mean gives us the idea of that how much amount of overall data have.
In other words, the mean is the foundation of the deviation of data from all data sets.
Mean = sum of data / Number of data
For example, if you have marks in 5 subjects like 40,45,44,46,48 then the mean will be
( 40 + 45+ 44 + 46 + 48) /5 = 44.6.
Given that,
Kara finds that the top 200200200 longest streaks in the world in June had an average of about 636363 wins in a row
It means the top 200200200 longest streaks worldwide in June have an average longest streak of 636363.
Hence " Kara finds that the top 200200200 longest streaks in the world in June had an average of about 636363".

The profit of a company , in dollars, is the difference between the company's revenue and cost. The cost C(x) and revenue, R(x) are functions for a particular company The x represents the number of items produced and sold to distributors
The maximum profit that the considered company can get is 142,400 bucks. That profit is earned when input x (the number of items produced) is 380
How to obtain the maximum value of a function?To find the maximum of a continuous and twice differentiable function f(x), we can firstly differentiate it with respect to x and equating it to 0 will give us critical points.
Putting those values of x in the second rate of function, if results in negative output, then at that point, there is maxima. If the output is positive then its minima and if its 0, then we will have to find the third derivative (if it exists) and so on.
The missing part of question is:
" [tex]C(x)=2000+70x[/tex], [tex]R(x)=830x-x^2[/tex]
A. Determine the maximum profit of the company.
B. Determine the number of items that must be produced and sold to obtain the maximum profit"
The profit is the difference between the revenue and the cost, so we get:
[tex]P(x) = R(x) - C(x) = 760x - x^2 - 2000[/tex]
Finding its first and second rate with respect to x:
[tex]P'(x) = 760 -2x\\P''(x) = -2[/tex]
Equating first rate to 0 to get the critical values:
[tex]P'(x) = 0 \implies 760 = 2x \implies x = 380[/tex]
The second rate is < 0 for any x, x = 380 is minima, and x = 380 being only critical value, it is global maximum.
At x = 380, the profit evaluates to:
[tex]P(x) = 760x - x^2 - 2000\\P(380) = 760(380) - (380)^2 - 2000 = (380)^2 - 2000\\P(380) = 142400[/tex]
Thus, the maximum profit that the considered company can get is 142,400 bucks. That profit is earned when input x (the number of items produced) is 380

Find its zero's
3x² + 18x - 48 = 0x² + 6x - 16 = 0x² + 8x - 2x - 16 = 0x(x + 8) - 2(x + 8) = 0(x + 8)(x - 2) = 0x + 8 = 0 ⇒ x = - 8x - 2 = 0 ⇒ x = 2b)
The vertex of qudratic function is determined at x = - b/(2a)
Applied to this relation, the x- coordinate of vertex is
x = - 18/(3*2) = - 18/6 = - 3Find its y- coordinate
y = 3(-3)² + 18(-3) - 48 = 27 - 54 - 48 = -75The vertex is (- 3, - 75)

Recall that csc x = 1 / sin x and tan x = sin x / cos x. Substitute:
[tex]\displaystyle = \cos x \left(\frac{1}{\sin x} + \frac{\sin x }{\cos x}\right)[/tex]
Distribute:
[tex]\displaystyle = \frac{\cos x}{\sin x} + \frac{\cos x \sin x}{\cos x} \\ \\ \\ = \frac{\cos x}{\sin x} + \sin x[/tex]
Recall that cot x = cos x / sin x. Hence:
