3x-8y=24
y=x-8

systems by substitution
show all work

Answers

Just write down everything I have there all you have to do is replace the y with the y=x-8

The solution to the system of equations, 3x-8y=24 and y=x-8, is x = 8 and y = 0.

How to Solve a System of Equations?

To solve the system of equations using the substitution method, we'll solve one equation for a variable and substitute it into the other equation. Let's solve the second equation for y:

y = x - 8

Now, substitute this expression for y in the first equation:

3x - 8(x - 8) = 24

Expand and simplify:

3x - 8x + 64 = 24

Combine like terms:

-5x + 64 = 24

Subtract 64 from both sides:

-5x = -40

Divide by -5:

x = 8

Now substitute the value of x back into the second equation to find y:

y = 8 - 8

y = 0

So the solution to the system of equations is x = 8 and y = 0.

Which of the following cases involved Supreme Court justice Thurgood Marshall and ended segregation in American schools? A. Marbury v. Madison B. Plessy v. Ferguson C. California v. UFW D. Brown v. Board of Education of Topeka

Answers

The answer is D. Brown V. Board of Education of Topeka

Supreme Court Justice Thurgood Marshall was involved in the case that put an end to segregation in American schools, Brown v. Board of Education of Topeka. As a result, choice (D) is the right solution.

What is the Brown v. Board of Education of Topeka case?

In its historic case Brown v. Board of Education of Topeka, the U.S. Supreme Court declared that racial segregation in public schools is unconstitutional, even where the segregated schools are otherwise equal in quality.

The ruling substantially overturned the Court's Plessy v. Ferguson decision from 1896, which had declared that racial segregation statutes did not contravene the U.S. Constitution so long as the facilities for each race were of similar quality.

This principle became known as "separate but equal." Integration was made possible by the Court's judgment in Brown, which also served as a landmark victory for the civil rights movement and served as a template for numerous more impact litigation cases in the future.

Hence, option (D) is accurate.

What is the enharmonic of Cb

Answers

I am pretty sure that the enharmonic equivalent of C flat is B natural. N.B-B natural can also be called a A double-sharp.  

Answer: the right answer is B natural

Explanation: enharmonic is when two notes with different names (in this case Cb and B natural) have almost the same sound. In the scale, B and C are separated only by a semitone. Therefore, if we play a Cb, we will be playing B natural since there is no B#. The same thing will happen with E and F because they are separated by a semitone. So, if you play Fb, you will be playing E.

is morality always destined to be relative?

Answers

It depends how you look at it. We have laws and such built on moral principles, yet at the same time, people are slowly, but surely, starting to turn away from morals. 

ANSWER:

Yes, morality is always destined to be relative.

EXPLANATION:

This is because moral judgments can be true or false relative to something. In others words, there must be something present on which moral principles, ethics and judgement must be based in relation to something else. Morality is also considered to be relative because there is no specific set of rules or moral ethics that the society is required to follow. In fact, moral ethics are adapted as and when people feel the need for these in relation to some context or situation. In other words, moral ethics come into play only in relation to something happening.

B. moles or marks on the body

Witchcraft was the period of panic and hysteria in the 17th century and often regarded as most captivating chapters of American history. In North America, young girls started having mysterious screaming fits and on diagnosis, it was revealed that the girls have been bewitched. This began the dramatic and strange search for witches. However, witch hunters started looking for devil marks or witch marks on suspected women bodies. Witch marks included the variety of skin lesions such as red, blue, brown lesions or many time unusual moles and outlines.

Why did republicans in Congress refuse to let newly-elected southern representatives take their seats, after the civil war?

Answers

Republicans in Congress refused to seat southern representatives after the Civil War to enforce stricter reconstruction measures, like the ratification of the Thirteenth and Fourteenth Amendments, and to protect the civil rights of freedmen against policies like the Black Codes that aimed to maintain old societal structures.

Republicans in Congress refused to allow newly-elected southern representatives to take their seats after the Civil War for several reasons, key among them being the Radical Republicans' view that the southern states needed to undergo more significant restructuring and comply with newer, stricter requirements before being readmitted to the Union. Additionally, there was significant concern over the Black Codes, which were designed to suppress the rights of freedmen and maintain a societal structure reminiscent of antebellum servitude.

Following the Civil War, in an attempt to circumvent civil rights and the Thirteenth Amendment, many southern states enacted the Black Codes. Radical Republicans were outraged by these developments and refused to seat the southern representatives because they saw them as an attempt to restore Confederate ideologies. It was imperative for Radical Republicans that the southern states ratify the Thirteenth and Fourteenth Amendments, and establish universal suffrage for black men to ensure full civil rights for freedmen before being fully reintegrated into the Union.

The Reconstruction Acts of 1867 laid out these conditions, and until they were met, Republicans, bolstered by their control in Congress, would not allow former Confederate leaders and sympathizers to hold office. Their refusal to seat these representatives was also a reflection of the broader political and societal clash over how to rebuild the South and integrate freed slaves into American society as equal citizens.
