When graphing "AND" inequalites, shading looks like Shading that always connects the 2 dots.
What is inequality?An algebraic statement that connects two values that are not equal is referred to as an inequality in mathematics. Inequality signals state that one of the two variables on either side of the inequality could be greater than, greater than or equal to, less than, or less than or equal to another value.
If a linear inequality has a sign that is either (less than) or, you will shade below the boundary line (less than or equal to). In a linear inequality, if the sign is > (greater than) or, you will shade above the boundary line (more than or equal to).
Follow these steps:
Rearrange the equation so "y" is on the left and everything else on the right.
Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
Shade above the line for a "greater than" (y> or y≥)
or below the line for a "less than" (y< or y≤).

assume that a customer shops at a local grocery store spending an average of $ a week, resulting in a retailer profit of $ each week from this customer. assuming the shopper visits the store all 52 weeks of the year, calculate the customer lifetime value if this shopper remains loyal over a 10-year life span. also assume a percent annual interest rate and no initial cost to acquire the customer.
"The customer yields $780 per year in profits for this retailer."
Customer lifetime value (CLV) is a prediction of the total value a customer will bring to a business over their entire relationship with the company. Retailer profits refer to the financial gain a retailer makes after subtracting all costs, including the cost of goods sold, operating expenses, and taxes, from the revenue generated by their retail sales.
The customer spends $250 a week, so the retailer profits:
= $250 - $235= $15 from each visit.If the shopper visits the store every week for a year, the retailer profits:
= $15 x 52= $780 per yearIf this shopper remains loyal for a 10-year lifespan, the retailer profits:
= $780 x 10= $7,800This is the CLV without considering inflation or any other factors. To consider inflation, we can apply the 8% annual interest rate to calculate the present value of the future profits. The present value of $7,800 over 10 years with an 8% interest rate is approximately $5,100 (the exact value will depend on the method used to calculate the present value).

Solve the following system of equations algebraically. Give exact answers. Then explain what your solution indicates about the graph of the system.
[tex]\left \{ {{3x^{2}+y^{2} =16} \atop {x^{2}-y^{2} =4}} \right.[/tex]
The solution to the system is:
(x, y) = (2.236, 1), (-2.236, 1), (2.236, -1), or (-2.236, -1).
This represents two equations hyperbola and ellipse which intersect at exactly 4 points.
The system of equations, as follows:
3x² + y² = 16
x² - y² = 4
We can solve this system of equations by substitution.
Starting with the first equation, we can isolate y²:
y² = 16 - 3x²
Substituting that into the second equation, we get:
x² - (16 - 3x²) = 4
Expanding the right side:
x² - 16 + 3x² = 4
4x² = 4 + 16
4x² = 20
Dividing both sides by 4:
x² = 5
Taking the square root of both sides:
x = ±√5 = ± 2.236
With x found, we can substitute it back into the expression for y²:
y² = 16 - 3x²
y² = 16 - 3(√5)²
y² = 16 - 3(5)
y² = 16 - 15
y² = 1
Taking the square root of both sides:
y = ±1
So the solution to the system is:
(x, y) = (2.236, 1), (-2.236, 1), (2.236, -1), or (-2.236, -1)
This means the two equations are hyperbola and ellipse which intersect at exactly 4 points.

if you add 10 to every value of a data set, what happens to the standard deviation?
The standard deviation of the data set will increase by a factor of 10. This is because standard deviation measures how much variation or dispersion exists from the mean of a data set. Adding 10 to every value of the data set will increase the overall spread of the data and thus increase the standard deviation.
To prove this mathematically, let's consider a data set A with mean M and standard deviation SD. Let's add 10 to every value of the data set to get a new data set B. The mean of set B is M+10 and the standard deviation of set B is SD'. The formula for SD' is:
SD':[tex]\sqrt{(x_{1} -(M+10))^{2} +(x_{2} -(M+10))^2+ (x_{3}-(M+10))^2 +...+ (x_{n}-(M+10))^2)/n }[/tex] We can simplify this by substituting the values for the xi:
SD' =[tex]\sqrt{(((x_{1}-M-10)^2 + (x_{2}-M-10)^2 + (x_{3}-M-10)^2 +...+ (x_{n}-M-10)^2)/n) }[/tex] Now let's consider the original data set A and its standard deviation SD:
SD =[tex]\sqrt{(((x_{1}-M)^2 + (x_{2}-M)^2 + (x_{3}-M)^2 +...+ (x_{n}-M)^2)/n) }[/tex] ,We can substitute the values for xi in this formula as well:
SD= [tex]\sqrt{ (((x_{1}-M-10)^2 + (x_{2}-M-10)^2 + (x_{3}-M-10)^2 +...+ (x_{n}-M-10)^2)/n)}[/tex] If we compare SD and SD', we can see that they are identical, except that the value of M has been replaced with M+10. This means that when we add 10 to every value of the data set, the standard deviation increases by a factor of 10.

b) The system of equations has one solution.
c) The solution is obtained as x = -3 and y = 7.
What is a linear equation?
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
The two linear equations given are -
y = - 6x - 11 .... (1)
y = 4x + 19 .... (2)
Substitute equation (1) in (2) -
- 6x - 11 = 4x + 19
Collect all the like terms -
- 6x - 4x = 19 + 11
-10x = 30
x = 30 / -10
x = -3
Substitute the value of x in equation (1) -
y = - 6(-3) - 11
y = 18 - 11
y = 7
The two equations form a linear graph and intersect at point (-3,7).
So, there is only one solution to the system of equations.
Therefore, the solutions are x = -3 and y = 7.

The sketch field of given differential equation is attached in image .
A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.
Any two different points on a line can be used to calculate the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula.
The equation y′=f(x,y) gives you a slope at each point in the (x,y)-plane. And this is the slope a solution y(x) would have at x if its value was y. In other words, f(x,y) is the slope of a solution whose graph runs through the point (x,y). At a point (x,y), we plot a short line with the slope f(x,y).

The coterminal angle with -210° is -570°. This is because subtracting 360° from -210° gives us -570° which is between -720° and -360°.
To find an angle coterminal with -210° that is between -720° and -360°, we need to subtract 360° from -210°. By doing this, we end up with -570° which is the coterminal angle with -210° that lies between -720° and -360°. This is because angles on the circle can 'wrap around' infinitely, and when we subtract 360° from -210°, we end up with an angle that is still equivalent to -210°, but between the two values we are looking for.

Determine the maximum value of the function ????(x) = (x − x 2 )/(1 + 8x 2 ) and the value of x at which this occurs.
The maximum value of the function f(x) = (x − x²)/(1 + 8x²) is 1/4, and it occurs when x = 1/2.
A function is a mathematical relationship between input and output values.
In this problem, we have a specific function defined as
=> f(x) = (x − x²)/(1 + 8x²).
Let's start by analyzing the expression of the function.
The function is composed of two parts:
=> (x − x²) and (1 + 8x²).
The first part is a simple polynomial expression with degree 2. It represents a parabolic shape with a vertex located at (1/2, 1/4).
The second part, (1 + 8x²), is always positive, so it does not affect the shape of the function.
The maximum value of the function will occur when the first part, (x − x²), is at its maximum. Since this part is a parabolic shape with a vertex at (1/2, 1/4), the maximum value is 1/4.
So, the maximum value of the function
=> f(x) = (x − x2)/(1 + 8x²) is 1/4.
To find the value of x at which this occurs, we will have to find the x-coordinate of the vertex of the parabolic shape.
This can be done using the formula for the x-coordinate of the vertex of a parabolic equation, which is -b/2a.
Plugging in the values of a and b from the equation (x − x²) gives us
x = 1/2.

If the price of a school bus increased at the same rate as the CPI from 1970 to 1984, how much did a school bus cost in 1984?
The cost of a bus in 1984 is =$ 7360 and in 1992 is $28140.and CPI in 1950 is 20.5.
The consumer price index (CPI) is the index that shows how much prices have changed over time. This index mainly focuses on the retailer prices for market players. Usually, this index increases due to inflation.
Part(1)
% change in CPI (1984-70)
[tex]=\frac{36.8-100}{100} \\=-63.2 \ percentage \\=-0.632[/tex]
Cost of bus = 20000(1-0.632)=$ 7360
Part II
% change in CPI (1984-92)
[tex]=\frac{140.7-199}{100}[/tex]
=40.7%
= 0.407
cost of a bus in 1992 = 20,000(1+0.407)
= $28140
part (3)
% change in CPI (1950-84)=% change in price
[tex]\frac{100-x}{x}*100=[[20000-4100]/4100]*100\\100-x=3.878x\\=x=20.5\\the\ cpi\ in\ 1950\ was \ 20.5.[/tex]
The complete question is -
In 1984, a school bus cost $20,000. To answer each of the parts below, assume that the consumer price index (CPI) was 36.8 in 1970, 100 in 1984, and 140.7 in 1992.
Part I: If the price of a school bus increased at the same rate as the CPI from 1970 to 1984, how much did a school bus cost in 1970? By how much did the price of a school bus increase from 1970 to 1984?
Part II: If the price of a school bus increased at the same rate as the CPI from 1984 to 1992, how much did a school bus cost in 1992? By how much did the price of a school bus increase from 1984 to 1992?
Part III: If a school bus cost $4100 in 1950, and if the price of a school bus increased at the same rate as the CPI from 1950 to 1984, what was the CPI to the nearest tenth in 1950?

Step-by-step explanation:
Two brothers each purchase a new pair of hiking boots and two canteens. The hiking boots cost 34. 00 each. The total of their purchase wad 98. 0.
Write an equation and solve
The equation formed will be - cost × number of hiking boots + cost × number of canteens and the cost of canteens will be 15.
The equation that will be formed is -
Total cost of purchase = cost of hiking boots × number of hiking boots + cost of canteens × number of canteens
Keep the values in formula to find number of canteens, as it is the only value not provided in the question.
98 = 2×34 + 2× cost of canteens
Performing multiplication on Right Hand Side of the equation
98 = 68 + 2×cost of canteens
Rewriting the formula -
2× cost of canteens = 98 - 68
Performing subtraction on Right Hand Side of the equation
2× cost of canteens = 30
Cost of canteens = 30/2
Performing division on Right Hand Side of the equation
Cost of canteens = 15 each
