Answer:
slope = -3/2
Step-by-step explanation:
The slope of a line passing through the two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1/x2−x1.
We have that x1=2, y1=5, x2=8, y2=−4.
Plug the given values into the formula for slope: m= (-4)-(5)/ (8)-(2) = -9/6 = -3/2
the slope of the line is m = -3/2

Dave is making a rectangle garden bed after assembling it he finds that the bed has a width of three fourths of a foot and a length of nine and one-third feet as shown what is the area of the garden in square feet express your answer in simplest form
Answer:
7 square feet
Explanation:
The width of the rectangle is 3/4 ft and the length is 9 1/3 ft.
First, we need to convert 9 1/3 ft to a fraction, so
\(9\frac{1}{3}=9+\frac{1}{3}=\frac{9(3)+1}{3}=\frac{27+1}{3}=\frac{28}{3}\)Then, the length of the rectangle is 28/3 ft
Now, we can calculate the area of the garden as
\(\begin{gathered} \text{Area = Width x Length} \\ \text{Area = }\frac{3}{4}\times\frac{28}{3}=\frac{3\times28}{4\times3}=\frac{84}{12}=7 \end{gathered}\)Therefore, the area is 7 square feet.
How do you find the distance between the points shown? (C: 6, -4) and (D: 6, -8)
A. Subtract the distance between each point and the x-axis
B. Add the distance between each point and the x-axis
C. Subtract the distance between each point and the y-axis
D. Add the distance between each point and the y-axis
Answer:
A. Subtract the distance between each point and the x-axis.
Step-by-step explanation:
As the two points have the same x-coordinate, x = 6, it means they lie on the vertical line x = 6.
Therefore, the distance between the points can be found by subtracting the distance between each point and the x-axis.
In the given example, the points are C(6, -4) and D(6, -8).
To find the distance between a point and the x-axis, we simply take the absolute value of the y-coordinate of the point:
Distance between point C and the x-axis = |-4| = 4
Distance between point D and the x-axis = |-8| = 8
Subtracting the distances, we get:
Distance = 8 - 4
Distance = 4
Therefore, the distance between points C and D is 4 units.

Based on this information, of the next 2500 pizzas he sells, how many should he expect to be thick crust? Round your answer to the nearest whole number. Do not round any intermediate calculations.
Answer:
500
Step-by-step explanation:
Add the number of pizzas to find the total, 1020. Since there are 204 thick crusts out of the 1020 pizzas, we can conclude that there is a thick crust in every 5 pizzas. We can make the denominator 2500, making the fraction 500/2500, thus we know there will 500 thick crust pizzas out of the next 2500 pizzas he sells.

An independent basic service set (IBSS) consists of how many access points?
An independent basic service set (IBSS) does not consist of any access points.
In an IBSS, devices such as laptops or smartphones connect with each other on a peer-to-peer basis, forming a temporary network. This type of network can be useful in situations where there is no existing infrastructure or when devices need to communicate with each other directly.
Since an IBSS does not involve any access points, it is not limited by the number of access points. Instead, the number of devices that can be part of an IBSS depends on the capabilities of the devices themselves and the network protocols being used.
To summarize, an IBSS does not consist of any access points. Instead, it is a network configuration where wireless devices communicate directly with each other. The number of devices that can be part of an IBSS depends on the capabilities of the devices and the network protocols being used.

The incremental fuel costs for two generating units 4 and B of a power plant are given by the following relations:
dFA/dPA=0.06 PA+ 11.4 dFy/dPa=0.07 Pa + 10 where P is the power in MW and F is the fuel cost in rupees per hour.
(a) Find the economic loading of the two units when the total load to be supplied by the power station is 150 MW.
(b) Find the net increase in fuel cost per hour if the load is equally shared by the two units.
(a) The economic loading of unit 4 and B are 11.54 MW and 138.46 MW, respectively.
To find the economic loading of the two units when the total load to be supplied by the power station is 150 MW, we need to minimize the total fuel cost. Let x be the power generated by unit 4 and y be the power generated by unit B. Then, we have:
x + y = 150 (total load)
The total fuel cost C is given by:
C = F4(x) + Fb(y)
where F4(x) and Fb(y) are the fuel costs for units 4 and B, respectively. Using the given relations, we have:
F4(x) = 0.06x^2 + 11.4x
Fb(y) = 0.07y^2 + 10y
Substituting x = 150 - y, we get:
C(y) = 0.06(150-y)^2 + 11.4(150-y) + 0.07y^2 + 10y
Expanding and simplifying, we get:
C(y) = 0.013y^2 - 3.6y + 1710
To minimize C(y), we take its derivative with respect to y and set it equal to zero:
dC/dy = 0.026y - 3.6 = 0
y = 138.46 MW
Substituting y back into x = 150 - y, we get:
x = 11.54 MW
(b) The negative value that is -1297.5 indicates that there is a net decrease in fuel cost per hour if the load is equally shared by the two units.
To find the net increase in fuel cost per hour if the load is equally shared by the two units, we need to calculate the fuel cost for each unit when they generate half of the total load (i.e., 75 MW). Using the given relations, we have:
F4(75) = 0.06(75)^2 + 11.4(75) = 1282.5
Fb(75) = 0.07(75)^2 + 10(75) = 1312.5
Therefore, the total fuel cost is:
C = F4(75) + Fb(75) = 2595
If the load is equally shared by the two units, each unit generates 75/2 = 37.5 MW. The fuel cost for each unit is:
F4(37.5) = 0.06(37.5)^2 + 11.4(37.5) = 641.25
Fb(37.5) = 0.07(37.5)^2 + 10(37.5) = 656.25
Therefore, the total fuel cost is:
C' = F4(37.5) + Fb(37.5) = 1297.5
The net increase in fuel cost per hour is:
ΔC = C' - C = 1297.5 - 2595 = -1297.5

Please, let me get the answers in 15 mins. Explain what a
strategy canvas is and how it is used
A strategy canvas is a visual framework used to analyze and compare the strategic positioning of different companies or products within an industry.
It is a tool developed by W. Chan Kim and Renée Mauborgne, the creators of the Blue Ocean Strategy, to help organizations identify and create new market spaces by differentiating their offerings.
The strategy canvas consists of two axes: the horizontal axis represents the key factors that the industry competes on, and the vertical axis represents the offering level or degree of offering provided for each factor. By plotting the current state of competing products or companies on the canvas, organizations can gain insights into the competitive landscape and identify areas of opportunity for innovation and differentiation.
The strategy canvas helps visualize the competitive factors that are driving the industry and highlights areas of convergence or similarity among existing offerings. It allows organizations to identify untapped market spaces where they can create unique value propositions and redefine the competitive boundaries.
To use a strategy canvas effectively, organizations need to analyze the key factors that customers value in the industry and assess the relative performance of their offerings compared to competitors. By identifying the factors where they are underperforming and overperforming, organizations can focus on enhancing their value proposition by reallocating resources, investing in areas of differentiation, and eliminating or reducing elements that do not create significant customer value.
A strategy canvas is a powerful tool for strategic analysis and innovation. It helps organizations visualize the competitive landscape, identify areas for differentiation, and create new market spaces by providing a clear understanding of customer preferences and the competitive factors that drive industry success.

Answer:
x=6 and y=−6.
Step-by-step explanation:
Let's solve your system by elimination.
−4x−2y=−12; 4x+8y=−24
−4x−2y=−12
4x+8y=−24
Add these equations to eliminate x:
6y=−36
Then solve 6y=−36 for y:
6y=−36
y = -6
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
−4x−2y=−12
Substitute −6 for y in−4x−2y=−12:
−4x−(2)(−6)=−12
−4x+12=−12(Simplify both sides of the equation)
−4x+12+−12=−12+−12(Add -12 to both sides)
−4x=−24
x = 6
