To create a system of equations represented by two lines, we first need to determine the equations of these lines in the slope-intercept form, which is y = mx + b, where m is the slope of the line and b is the y-intercept.
Let's say the two lines are represented by:
Line 1: Blank space 1 emptyx + Blank space 2 emptyy = Blank space 3 empty
Line 2: Blank space 4 emptyx + Blank space 5 emptyy = Blank space 6 empty
Let's multiply the first equation by Blank space 5 empty and the second equation by -Blank space 2 empty, so we get:
Line 1: Blank space 1 emptyx + Blank space 2 emptyy = Blank space 3 empty
Line 2: -Blank space 4 emptyBlank space 5 emptyx - Blank space 2 emptyBlank space 5 emptyy = -Blank space 6 emptyBlank space 2 empty
Now, if we add these two equations, we can eliminate the y variable:
(Blank space 1 emptyx - Blank space 4 emptyBlank space 5 emptyx) + (Blank space 2 emptyy - Blank space 2 emptyBlank space 5 emptyy) = Blank space 3 empty - Blank space 6 emptyBlank space 2 empty
Simplifying, we get:
(Blank space 1 empty - Blank space 4 emptyBlank space 5 empty) x = Blank space 3 empty - Blank space 6 emptyBlank space 2 empty
Therefore, the solution to the system is:
x = (Blank space 3 empty - Blank space 6 emptyBlank space 2 empty) / (Blank space 1 empty - Blank space 4 emptyBlank space 5 empty)
Now, we need to find the value of y by substituting x into one of the equations. Let's use the first equation:
Blank space 1 emptyx + Blank space 2 emptyy = Blank space 3 empty
Substituting x, we get:
Blank space 1 empty(Blank space 3 empty - Blank space 6 emptyBlank space 2 empty) / (Blank space 1 empty - Blank space 4 emptyBlank space 5 empty) + Blank space 2 emptyy = Blank space 3 empty
Simplifying, we get:
y = (Blank space 3 empty(Blank space 1 empty - Blank space 4 emptyBlank space 5 empty) - Blank space 2 emptyBlank space 6 empty) / (Blank space 1 empty - Blank space 4 emptyBlank space 5 empty)
Therefore, the solution to the system is the ordered pair (x, y) = (Blank space 3 empty - Blank space 6 emptyBlank space 2 empty / Blank space 1 empty - Blank space 4 emptyBlank space 5 empty, (Blank space 3 empty(Blank space 1 empty - Blank space 4 emptyBlank space 5 empty) - Blank space 2 emptyBlank space 6 empty) / (Blank space 1 empty - Blank space 4 emptyBlank space 5 empty)).

How do ocean currents effect the air temperature for Luderitz and Florianopolis?
Answer:
Ocean currents can have a significant effect on air temperature in coastal areas like Luderitz and Florianopolis.
Luderitz, located on the Atlantic coast of Namibia, is influenced by the cold Benguela Current which flows northward along the coast from Antarctica. This current cools the air above it, resulting in lower air temperatures in Luderitz compared to other locations at a similar latitude.
Florianopolis, on the other hand, is located on the Atlantic coast of Brazil and is influenced by the warm Brazil Current, which flows southward along the coast from the equator. This current warms the air above it, resulting in higher air temperatures in Florianopolis compared to other locations at a similar latitude.
Therefore, in both cases, the ocean currents play a significant role in determining the air temperature of the coastal areas.

Is it true that The earliest evidence of accounting is the double-entry system used in the thirteenth century?
Answer:
No
Explanation:
No, it is not true. While the double-entry system is an important and widely used method in accounting, there is evidence of accounting practices dating back to ancient civilizations such as the Babylonians and Egyptians. The ancient Greeks and Romans also had various forms of accounting and record-keeping. However, the double-entry system as we know it today was first described by Italian mathematician Luca Pacioli in his book "Summa de Arithmetica, Geometria, Proportioni et Proportionalità" in the 15th century.
2018 poll of 2232 randomly selected U.S. adults found that 40.86% planned to watch at least a "fair amount" of a particular sporting event in 2018.
In 2014, 47% of U.S, adults reported planning to watch at least a "fair amount."
a. Does this sample give evidence that the proportion of U.S. adults who planned to watch the 2018 sporting event was less than the proportion who planned to do so in 2014? Use a 0.05 significance level.
b. After conducting the hypothesis test, a further question one might ask is what proportion of all U.S. adults planned to watch at least a "fair amount" of the sporting event in 2018. Use the sample data to construct a 90% confidence interval for the population proportion. How does your confidence interval support your hypothesis test conclusion?
a. Let p

be the proportion of U.S. adults who planned to watch at least a "fair amount" of the 2018 sporting event and p

Our p-value is P(z<−6.38)=0.000000000002.
Since our p-value is less than our significance level of α=0.05, we reject the null hypothesis. There is evidence to suggest that the proportion of U.S. adults who planned to watch the 2018 sporting event was less than the proportion who planned to do so in 2014.

CI=(0.4002,0.4170)
We are 90% confident that the true proportion of U.S. adults who planned to watch at least a "fair amount" of the 2018 sporting event is between 0.4002 and 0.4170.
Our confidence interval does not include 0.47, the proportion of U.S. adults who planned to watch at least a "fair amount" of the sporting event in 2014. This supports our hypothesis test conclusion that the proportion of U.S. adults who planned to watch the 2018 sporting event was less than the proportion who planned to do so in 2014.
When a plant is not strong enough to support its own weight, what is most likely the problem? O A. The plant is producing too many polysaccharides. B. The plant is not producing enough cellulose. C. The plant needs more monosaccharides to add strength. D. The plant does not have enough starch. ✔ Correct
(D) The plant is not producing enough cellulose
Yes, you are correct. When a plant is not strong enough to support its own weight, the most likely problem is that the plant is not producing enough cellulose. Cellulose is a complex carbohydrate that provides structural support to plant cell walls. It forms strong fibers that help plants maintain their shape and rigidity. If a plant does not produce enough cellulose, its cell walls may be weak, leading to a lack of structural support and an inability to withstand the weight of the plant.[tex][/tex]
How does lack of community participation contribute to poor service delivery
Answer:
In summary, lack of community participation can contribute to poor service delivery by limiting feedback, inadequate needs assessment, limited accountability, and limited resources. Therefore, it is important to involve communities in the planning, implementation, and monitoring of public services to improve service delivery.
Explanation:
Lack of Feedback: If the community is not involved in the planning, implementation, and monitoring of public services, it becomes difficult for authorities to obtain feedback on the effectiveness of the services provided. Without feedback, it is difficult to identify areas that need improvement, and this can result in poor service delivery.
Inadequate Needs Assessment: When community members are not involved in the needs assessment process, it becomes difficult to identify the specific needs of the community. This can result in services that are not tailored to the specific needs of the community, leading to poor service delivery.
Limited Accountability: Community participation provides an avenue for holding service providers accountable for their actions. When community members are not involved in monitoring the delivery of services, it becomes difficult to hold service providers accountable for their actions. This can result in poor service delivery, as service providers may not be held accountable for their shortcomings.
Limited Resources: Community participation can also lead to the identification of additional resources that can be used to support the delivery of public services. When community members are not involved, it becomes difficult to identify additional resources that can be used to support service delivery. This can result in poor service delivery due to limited resources.

Before the radio and telephone were invented, some groups used patterns of drumbeats to send information to one another.
Which statement ,begin emphasis,best,end emphasis, explains how the patterns of drumbeats transferred information from one group to another?
Answer options with 4 options
A.
The different shapes of the drums produced different sounds.
B.
The pattern of drumbeats represented different words or phrases.
C.
The groups used different drums during different times of the year.
D.
The drumbeats were so loud that they could be heard from great distances.
The statement that best explains how patterns of drumbeats transferred information from one group to another is option B: "The pattern of drumbeats represented different words or phrases."
Groups that used drumbeats to communicate developed complex systems of rhythms and patterns that could convey specific meanings, much like a language. Different rhythms and patterns were associated with different words, phrases, or messages.
For example, a certain pattern of beats might represent a warning of danger, while another pattern might indicate the arrival of an important visitor. By varying the rhythm and duration of the beats, and by using different combinations of beats, the drummers could convey a wide range of meanings and messages.
Drum communication was particularly useful for groups that lived in areas with rugged terrain or dense forests, where it was difficult to communicate over long distances using spoken language.
The sound of the drums could carry for miles and was easily distinguishable from other sounds in the environment. In addition, because the drummers could use a code that was known only to their group, they could communicate privately without fear of interception or misinterpretation by outsiders.
In conclusion, the patterns of drumbeats used by certain groups to send information to one another represented different words or phrases. These rhythms and patterns allowed the drummers to convey a wide range of messages over long distances and in difficult terrain.
