Can you write a 5 sentence summary about the substitution method?

Answers

Answer:

The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.

which graph best represents a function with a domain of all real numbers less than 5?

Answers

It's graph(B).

Imma 100% sure 'bout this. Mark it!

The domain of a graph is the list of possible x values of the graph

Graph B has the domain of all real numbers less than 5

From the list of options, we have the following observations.

For graphs A and C,

The curves extend across the x-axis.

So, the domain is: [tex](-\infty,\infty)[/tex]

For graph D,

The curve extends in the negative x-axis, but stops at [tex]x = 0[/tex], with an open circle

So, the domain is: [tex](-\infty,0)[/tex]

For graph B, the curve extends in the negative x-axis, but stops at [tex]x = 0[/tex], with an open circle

So, the domain is: [tex](-\infty,5)[/tex]

The domain [tex](-\infty,5)[/tex] means that:

All real numbers less than 5

Hence, the domain is illustrated on graph B

Read the Becoming a National Treasure.The Grand Canyon has been a well-known destination since before the 1890s. However, its journey to becoming a national park did not happen right away. Though settlers had been traveling to the canyon for decades, the first high-profile visit occurred in 1903. At that time, President Roosevelt visited the canyon for the first time. After viewing the canyon, he spoke about the awe he felt. He stated that it should be protected, so that every American could visit it one day. Even though Roosevelt talked about the importantce of protecting the park, it was still not named as a national park.It was not until 1906 that Roosevelt created the Grand Canyon Preserve. Then, in 1908 he created the Grand Canyon National Monument. This told Americans that the park was of cultural importantce to the country. Though the first Senate bills to make the Grand Canyon a national park were in 1882 and 1886, other bills followed in 1910 and 1911. It was not until February 1919 that the Grand Canyon was officially named a national park. The Grand Canyon National Park Act was finally signed in 1919 by President Woodrow Wilson.The naming of the Grand Canyon as a national park is known as an early conservation effort. Some people had been hoping to create a man-made dam in the Colorado River within the park. However, they could not build the dam because the area was protected. The borders of the park expanded in 1975. During this year, the Marble Canyon National Monument became a part of the Grand Canyon National Park. Finally, in 1979, the United Nations Educational, Scientific, and Cultural Organisation (UNESCO) named the park a World Heritage Site. By becoming a World Heritage Site, the Grand Canyon National Park became protected by international law.Select a detail from the text that demonstrates the overall text structure. A.
