Use Two Sets Of Coordinates To Write An Equationto Describe The Relationship.

Answers

Answer 1

Answer/Step-by-step explanation:

An equation that describes the relationship can be written as [tex] y = mx [/tex].

Using the two sets of coordinates, (2, 140) and (4, 280), calculate the slope (m) as shown below:

[tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{280 - 140}{4 - 2} = \frac{140}{2} = 70 [/tex]

Substitute m = 70 into [tex] y = mx [/tex]

The equation would be:

[tex] y = 70x [/tex]

This equation can be interpreted as follows:

The heart's resting rate is 70 beats each minute.

Answers

Answer:x =24

Step-by-step explanation: If we reverse that we will get x= 32x3/4 which is 24

Answer:

x = -24

Step-by-step explanation:

(-4/3)x -6 =26

Add 6 to both sides:

(-4/3)x = 32

(-4/3) = -1.33333333

divide both sides by -1.33333333

x = -24

Substitute:

(-4/3)(-24) -6 =26

32 - 6 = 26

26 = 26

x = -24

Corresponding angles are in the same direction from their respective intersections. Here, the angles are both northwest of the point where the lines cross. The angles are corresponding.

Answer:

  19) x = number of people; y = cost

  20) (people, cost) = (15, 120) and (25, 200)

  21) the rate of change is $8 per person

  22) y = 8x

  23) $320

Step-by-step explanation:

19) The problem statement tells you x is the number of people and y is the cost.

__

20) Writing the pairs (people, cost), we have ...

  (15, 120) and (25, 200)

__

21) The rate of change can be found from the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (200 -120)/(25 -15) = 80/10 = 8

The rate of change is $8 per person.

__

22) In point-slope form, the rule is ...

  y -y1 = m(x -x1)

  y -120 = 8(x -15)

  y = 8x -120 +120

  y = 8x

__

23) For x=40, y = 8(40) = 320

A party for 40 people will cost $320.

If I pay $600 in interest for my simple interest loan for $10,000 at an
interest rate of 3%, how long did I have the loan for?

Answers

Answer:

2 periods

Step-by-step explanation:

Simple interest is compounded one time, usually annually, although it could be less time or longer. Thus I answer 2 periods. If your choices include 2 years, that is most likely the answer.

To find the answer,

$10,000 x .03 = $300.

$600 / $300 = 2 periods.

There is a blue lining around the earth called earths atmosphere, and that blue protects us from the suns harmful rays, keeps us from freezing during the cold seasons, and protects us from space (as you may know space does not have oxygen to where humans can breath normally). Wait what was that.. What can you do to stop adding greenhouse gases to the earth? Well thats exactly what I am going to educate you on. So just sit back and pay attention.So as I said adding too much greenhouse gases puts animals and humans in danger. I know what your thinking. How bad can greenhouse gases be to put animals and humans in danger. Actually, it is so bad it adds heat to the earth and even when its hot enough already. Every year it feels hotter and hotter in the summer. Thats because humans are adding the greenhouse gases to the earths atmosphere. In fact, most humans are adding greenhouse gases to the atmosphere without knowing it. If you think about it, the bigger our population: the more resources we need to live. One of the biggest resources humans need to live is energy. Most of the things we use everyday uses energy. For example: light, cars, cell phones, computers, TVs, and video games. There is more than that but that is all I can think of for now. The greenhouse effect is a natural process that causes the earth to warm up. This process involves the sun and many gases in our atmosphere.Our energy comes from fossil fuels, which is oil, coal, and natural gas. Fossil fuels are an important resource for energy. Fossils are formed when plants and animals die and are covered in sediment and pressed for many thousands of years. Climate change is very dangerous. That is why I need to explain to you what you can do around and in your home to help stop global warming. Global warming is a process that is caused by fossil fuels, greenhouse gases, and the greenhouse effect. So listen carefully if you are interested in knowing how to stop global warming starting with you. The biggest factor of climate change is the use of energy which as I said is made from the burning of fossil fuels. So when you are at home and a light or the TV is on and it is not in use it would be a big help to turn it off and conserve energy within your home. Carbon dioxide is a harmful gas to humans and animals so planting some trees or flowers also helps a lot. When you are driving it adds more greenhouse gas because you use fuel to fill up your tank, so using a public transportation or riding a bike will help more than anything else when you are outside. When you are in the kitchen cooking (I know even cooking adds greenhouse gases to the earth) using a toaster or a microwave to cook some food will save much more energy than using an oven . Another big way that energy is used within your kitchen is a dishwasher. Dishwashers use a lot of water and produce a lot of heat, so hand washing a drip drying your dishes is a much more easier way to save energy. And last but not least when your at school recycling stuff that can be recycled instead of throwing it away is also a way you can help stop global warming. Making sure the computers you use in your classroom are all off or on sleep mode when not in use is a even better way to help in school. But the most helpful when trying to help stop global warming is riding your bike or skateboard to school instead of asking your parents for a ride. So I hope you enjoyed my essay and remember helping stop global warming is a good deed many people dont think of. Save energy the best you can and have a wonderful day! 12.
