Find the solution of the system
-2x-2y=28
2x+4y=-42

Answers

Ok. So I used Elimination method. You could also use Substitution. Put the two equations on top of each other, as if you were adding and subtracting. Then decide whether to add of subtract, as the whole purpose of this method is to eliminate a variable. The x was eliminated. Then you can solve to get y.

Going back to one of the ORIGINAL equation, sub in your y and solve. Then you can put your x and y into an order pair (x,y). That pair is your answer!

Hope that helps! If more clarification is required, leave a comment!

Answers

Answer:

The reaction in the diagram is right.

Explanation:

In complete combustion, hydrocarbon fuels burn in the presence of high concentration of oxygen that produces carbondioxide gas and water which are releases in the atmosphere. Complete combustion takes place only when there is oxygen present in large amount whereas incomplete combustion occurs when the oxygen in the environment is limited so complete combustion required more oxygen as compared to incomplete combustion.

Hich statement best describes a change that usually takes place in the human body when the heart rate increases as a result of exercise?

Answers

Complete Question:

Which statement best describes a change that usually takes place in the human body when the heart rate increases as a result of exercise?

Group of answer choices.

A. More oxygen is delivered to muscle cells.

B. Blood cells are excreted at a faster rate.

C. The rate of digestion increases.

D. No hormones are produced.

Answer:

A. More oxygen is delivered to muscle cells.

Explanation:

An aerobic exercise refers to all forms of physical activity that an individual engages in, so as to increase the heart rate (from low to high intensity) in response to the level of oxygen required by any activated or working muscle in the human body.

Generally, aerobic exercise help various individuals to prevent cardiovascular diseases because it makes the heart to beat faster (heart rate increases) to enable it supply more oxygen, which makes the heart to effectively and efficiently pump blood more.

Some examples of aerobic exercise (cardiofitness activity) includes cycling, swimming, jogging, walking, skiing etc.

Hence, the statement which best describes a change that usually takes place in the human body when the heart rate increases as a result of exercise is that more oxygen is delivered to muscle cells.

Ocean basin
Divergent boundary
Transform boundary
Convergent boundary

Answers

Answer:

transform boundary

Explanation:

A transform boundary is when two plates slide past each other

divergent boundary is when two plates move away from each other

convergent boundary is when two plates crash into each other

A boundary formed when two plates move past each other is  transform boundary. among all the given options, the correct option is option C.

What is transform boundary?

A transform border is when two tectonic plates of the Earth pass one another. The interaction between the two plates as they pass one another might result in localized faults or fissures. The fundamental description of a transform border is as follows, however they are more complex than that.

Divergent borders and convergent boundaries are two more forms of boundaries that are different from transform boundaries. The tectonic plates interact with one another at convergent borders while they separate from one another at divergent limits. A boundary formed when two plates move past each other is  transform boundary.

Therefore, the correct option is option C.

Eventually, the environment will be unable to support the production of wildebeests, this will cause there to be a loss of vegitation that then causes a food shortage, and then the wildebeests will starve.  

Explanation:

It's a very unhappy process, but those herds who don't migrate to another pasture will starve and die. The death will depopulate the savanna and give the fields some time for regrowth and the cycle will begin again.

Explain why the Moon, stars, and sun appear to change positions in the sky.

Answers

Answer:

because the earth rotates and revolves around a axis causing the stars sun move to change position and shape

The moon, stars, and sun appear to change positions in the sky because of the rotation of the earth on its axis, and due to the combination of the earth's rotation and its orbit around the sun, as well as the moon's orbit around the earth, their positions change.

What are the positions change of the moon, stars, and sun?

The Earth rotates on its axis once every 24 hours, causing the Sun, Moon, and stars to appear to move across the sky; this motion is caused by the Earth's rotation, and the position of the Sun in the sky also changes throughout the year due to the Earth's orbit around the Sun. As the Earth moves in its elliptical orbit, the angle of the Sun's light hitting the Earth changes, and the Moon appears to change positions in the sky because of its orbit around the Earth, so all three change positions.

Hence, the moon, stars, and sun appear to change positions in the sky because of the rotation of the earth on its axis.
