An ordered pair that satisfies all the equations in a linear system of equations is called a(n) __________ of the linear system.​

Answers

Answer 1

Answer:solution

Step-by-step explanation:

Answer 2

An ordered pair that satisfies all the equations in a linear system of equations is called a: solution of the linear system.

A linear function is a function that has a positive relationship between its variables.

Hence, an increase in one variable (input variable) causes an increase in the other variable (output variable) because the variables are directly proportional.

Mathematically, the graph of a linear function is a straight-line and its slope is always constant.

On a related note, a linear system of equation is an algebraic equation of the first order with two variables and each of its term having an exponent of one.

Generally, a system of linear equations in two variables must have at least two solution.

In conclusion, a solution of the linear system is an ordered pair that satisfies all the equations in a linear system of equations.

speak both languages.
a) Find the number of people who speak both languages.
b) Also illustrate the above information in Venn diagram.​

Answers

Answer:

Universal set is 80

Number of people that speak Nepali is 50

Number of people that speak English is 45

Number of people that do not speak both is 7

a. Number of people that speak both languages is 22

b. As above

Step-by-step explanation:

a. Let make number of people that speak both languages x

To get x

(50-x) + (45-x) + x + 7 = 80

(50-x) + (45-x) + x = 80 - 7

(50-x) + (45-x) + x = 73

Open bracket

50-x+45-x+x= 73

50+45-2x+x = 73

95 - x = 73

-x = 73 - 95

-x = -22

x = 22

Therefore, number of people that speak both languages is 22

b. To get venn diagram

Number of people that speak Nepali is 50 - 22 = 28

Number of people that speak English is 45 - 22 = 23

Therefore, total = 28+23+22+7 = 80

she drank 14 ounces of her water, she has 28 ounces left, just divide 42 by 3

Answer:

1)14oz

2)28oz

Step-by-step explanation:

1) To find the amount of water is left in the bottle you want to substract 1/3 so the first thing you want to do is find what 1/3 of 42 is. So do this: (This is also 42/3)

42*1/3=14

So we now know that 14 is 1/3 of 45 which is the first answer. To find the second answer you want to substract 14 from 42 which is 28.

So that means she has 28 oz of water left when she gets there.

Step-by-step explanation:

The standard height from the floor to the bull’s-eye at which a standard dartboard is hung at 5 feet 8 inches. A standard dartboard is 18 inches in diameter. Suppose a standard dartboard is hung at standard height so that the bull’s-eye is 10 feet from the wall to its left. Sasha throws a dart at the dartboard that land at point 10.25 Feet from the left wall and 5 feet above the floor. Does Sasha’s dart land on the dartboard? Drag the choices into the boxes to correctly complete the statements.

Answers

Answer:

Hello! I'm sorry I couldn't get to your question sooner. I just completed this quiz!

The equation of the circle that represents the dartboard is (x-10)^2 + (y-17/3)^2 = 9/16, where the origin is the lower-left corner of the room and the unit of the radius is feet.  

The position of Sasha's dart is represented by the coordinates (10.25,5). Sash's dart does land on the dartboard.

This quiz was completed on k12, lesson 3.03.

The question is an illustration of equation of circles.

The equation of the dartboard circle is: [tex]\mathbf{(x - 10)^2 + (y - \frac{17}3)^2 = \frac 9{16}}[/tex]Sasha's dart lands on the dartboard because

From the question, we understand that:

[tex]\mathbf{h = 5\ ft\ 8\ in }[/tex] ---- the height at which the dartboard was hung

[tex]\mathbf{d = 18\i n }[/tex] ---- the diameter of the dartboard

[tex]\mathbf{B = 10ft}[/tex]  --- the bull's eye

[tex]\mathbf{D = (10.25ft, 5ft)}[/tex] --- Sasha's dart

Equation of the circle

First, we convert all units to feet

This is done by dividing inches units by 12

[tex]\mathbf{h = 5\ ft\ 8\ in }[/tex]

[tex]\mathbf{h = 5\ ft\ + \frac{8}{12}\ ft }[/tex]

[tex]\mathbf{h = 5\ ft\ + \frac{2}{3}\ ft }[/tex]

Take LCM

[tex]\mathbf{h = \frac{15 + 2}{3}\ ft }[/tex]

[tex]\mathbf{h = \frac{17}{3}\ ft }[/tex]

[tex]\mathbf{d = 18\i n }[/tex]

[tex]\mathbf{d = \frac{18}{12}ft}[/tex]

[tex]\mathbf{d = \frac{3}{2}ft}[/tex]

Divide by 2 to calculate radius

[tex]\mathbf{r = \frac{3}{2*2}ft}[/tex]

[tex]\mathbf{r = \frac{3}{4}ft}[/tex]

The equation of the circle is represented as:

[tex]\mathbf{(x - a)^2 + (y - b)^2 = r^2}[/tex]

In this case:

[tex]\mathbf{a = B = 10ft}[/tex] -- the distance between the bull's eye and the wall

[tex]\mathbf{b = h = \frac{17}{3}\ ft }[/tex] ---- the height at which the dartboard was hung

So, we have:

[tex]\mathbf{(x - a)^2 + (y - b)^2 = r^2}[/tex]

[tex]\mathbf{(x - 10)^2 + (y - \frac{17}3)^2 = (\frac 34)^2}[/tex]

Evaluate the exponents

[tex]\mathbf{(x - 10)^2 + (y - \frac{17}3)^2 = \frac 9{16}}[/tex]

Hence, the equation of the circle is: [tex]\mathbf{(x - 10)^2 + (y - \frac{17}3)^2 = \frac 9{16}}[/tex]

Does Sasha’s dart land on the dartboard?

Yes her dart lands on the dartboard because

[tex]\mathbf{D = (10.25ft, 5ft)}[/tex] is within the circumference of the dartboard

Lesson4Words to KnowUnderstanding the following words will help you read this lesson:TERMS & NAMESprimary sourcesecondary sourceoral historyHow HistoriansStudy the PastBuild on What You Know You may know where your parents or ancestors came from and some of the stories about them. Relatives and their stories help people understand their family history. Now learn what historians use to help them understand the past.Understanding the PastESSENTIAL QUESTION What questions do historians ask to help them understand the past?People investigate their family history to find out about their ancestors. In the process, however, they also find out about themselves. We study world history for the same reasons.Why Study History? What has already happened to a person, a family, or asociety affects what will occur today and in the future. But history is much more than simply recounting and studying past events. Examining a historical event also involves studying a societys culture, religion, politics, and economics.When historians examine past events, they try to find patterns. They look for causes and effects that explain how and why events happened. They also try to understand why some ideas and traditions last and why others die out. Just as important, historians attempt to see the past through the eyes of the people who lived it. By doing so, historians gain greater insight into human nature and answer important historical questions.Asking Historical Questions As historians study the past, they ask themselves questions like those below. These questions help historians compare different societies and draw conclusions about the past. How have groups or societies interacted, and what have been the results? How have leaders governed societies? How have belief systems developed and changed? How have societies dealt with differences among their people? How have societies tried to protect peoples security? How are societies similar and different?Why do we study history?The Historians ToolsESSENTIAL QUESTION What methods do historians use to help them answer questions about what happened in the past? When you hang up a picture, you use a hammer to pound in the nail. Historians also use tools to do their job. These tools include primary sources, secondary sources, and oral history.Primary Sources A primary source is something written or created by a person who witnessed a historical event. You will learn about an ancient primary source on the next page. Primary sources include letters, diaries, eyewitness articles, videotapes, speeches, and photographs. Artifacts, such as the human-made tools, are also primary sources.loading...How Knowledge of the Past ChangesESSENTIAL QUESTION What steps do historians take as they answer historical questions?Detectives use fingerprints and other evidence to solve crimes. Historians act as detectives too. They use evidence from primary, secondary, and oral sources.Fact or Fiction? Historical evidence isnt always as simple as a bloodstain at a crimescene. Historians sometimes have more information than they can use when they try to answer a question. They must sort through all of the information and choose whats most important and most trustworthy as evidence. In addition, sometimes what historians thought was true turns out to be false. For instance, one historian proved that the so-called mummyscurse was false. According to legend, the curse would kill anyone who entered the tomb of an ancient Egyptian ruler. Many people believed the curse had caused the death of English archaeologist Lord Carnarvon. He died suddenly in 1923, shortly after entering the tombof ancient Egyptian ruler King Tut. People believe that the other archaeologists who had entered the tomb between 1923 and 1926 would also die as a result of the curse. However, a historian later examined the archaeologists death records. Their average age at death was70 years. The evidence did not support the existence of the mummys curse.Drawing Conclusions The mummys curse was easy to disprove. But not all historical questions are so easily answered. Sometimes different historians arrive at different conclusions based on the same facts.Answer the following questions2. What is the difference between primary and secondary sources?
