One equation in a system isy = 2x - 4. Which equation gives the system no solution?

y = 2x - 4

y = -2x + 4

y = 2x + 9

y = 14x - 4

Answers

Answer 1

Answer:

number 3 will be right

Step-by-step explanation:

Answer 2

The correct statement is : y=2x+9

What are linear equations?

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here: The linear equation is y=2x-4

Now the equation y=2x+9

equating both linear equations are

2x-4=2x+9

-4=9 which is not possible

Thus the incorrect equation that gives no solution is y=2x+9

You can write such a cubic polynomial in terms of its roots using the factor theorem:

Answer:

130.5ft²

Step-by-step explanation:

Hello There!

The figure shown is a composite figure ( so we can't find the area of it using one formula )

That being said we want to break the irregular figure into regular figures in which the area can simply be found using a formula

The figure would be broken in to the following shapes

A rectangle with a width of 4 ft and a length of 9 ft

A rectangle with a width of 8 ft and a length of 9 ft

A triangle with a height of 5 ft and a base of 9 ft

Now that we have broken the irregular figure into regular shapes we want to find the area of each individual shape

For the smaller rectangle:

The area of a rectangle can simply be calculated by multiplying the width and length

So A = 9 * 4

9 * 4 = 36

so the area of the smaller rectangle is 36ft²

For the larger rectangle

Once again the area can simply be found by multiplying the width and length

A = 8 * 9

8 * 9 = 72

so the area of the larger rectangle is 72ft²

For the triangle

To find the area of a triangle we want to use this formula

[tex]A = \frac{bh}{2}[/tex]

where b = base and h = height

We have already identified the base and height so all we have to do is plug in the values into the formula

[tex]A=\frac{5*9}{2} \\5*9=45\\\frac{45}{2} =22.5[/tex]

so the area of the triangle is 22.5ft²

Finally we add the areas of each regular figure

22.5 + 72 + 36 = 130.5

so we can conclude that the area of the composite figure is 130.5ft²

Given that,

The quadratic equation,

x²  - 6x - 7  = 0

we can calculate the roots of the equation by using the formula:

x   = -b + √(b² - 4ac) / 2a

In the given equation,

a = 1

b = -6

c = -7

x  = -(-6)  + √((-6)² - 4x1x(-7)) / 2

FINAL DUE TONIGHT!!! SUMMARIZE THIS INTO TWO PARAGRAPHS INSTEAD OF FOURThe sixteenth, seventeenth, and eighteenth centuries changed the world in dramatic ways. But probably, the biggest change the world saw or has ever seen was the finding and conquest of the Americas. Many are theories as to what led both the Spanish and Portuguese empires to seek these voyages, but the truth of the matter is that the main reasons that pushed Spain to support Cristopher Columbus in his trip in 1492 were, first, the desire to discover and open new trade routes to the Indies. And the second reason was evangelization, which the two Spanish monarchs believed would be empowered by colonization.When the Spanish first arrived in the Americas, their first encounter was not with any big Native tribes or settled civilizations. It was not until later on, in 1519, that the Spanish encountered true Native American civilization. And the first to find this was Hernn Corts, who between 1519 and 1521, led a war against the Aztec Empire, one of the biggest and most important of the entire continent. The Aztecs were settled in the Gulf of Mexico, in what is today Mexico itself. The Aztecs, led by Moctezuma II were really advanced people, with a federal-like way of government, cities, technology, and organized society. But like all well-organized and advanced societies, problems arose. The first was that through contact with the Spanish, many diseases unknown until then diminished the number of Natives and also because of weaponry, which allowed the Spanish to finally overcome the Aztec forces.The second empire was the Inca Empire, in what is today Peru, specifically in Cusco. Unlike its sister empire in Mexico, the Incas did not have wheeled vehicles and they did not use farm animals. They did not have a currency and they survived on the exchange of goods, instead of a market. What made them really advanced was their ability in masonry and the use of stone. Their architecture was really advanced and like the Aztecs, their cities were impressive. They also had a centralized system of government led by a king, who at the time of the arrival of the Conquistadors was Atahualpa, and the king was considered the owner of everything within the empire. They also had a very advanced system of roads that connected the central city of Machu Picchu with the rest of the Empire. It was Francisco Pizarro who in 1526 moved from Panama to the Andean region and found himself at Machu Picchu. After several trips, finally, between 1532 and 1533, Francisco Pizarro and the Spanish were able to take control of the vast Inca Empire.In the end, most of the Americas, save what is nowadays Brazil, which ended in the hands of Portugal, became part of the enormous Spanish Empire. The result was a group of colonies from which the Spanish derived the precious metal of gold and which made them really rich. The Natives, at first were enslaved by the Spanish until through intervention of the Church, black people were brought in to prevent the death of the Natives. The disease also decimated the Native population in the Americas. There was a lot of racial mixing between the Spanish and Natives, which gave origin to many new skin colors, typical of Spanish America.
