Answer:

The equation of the line is:

y = 3x

Step-by-step explanation:

Given the table

x             y

0            0

1             3

2            6

3            9

4            12

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

m is the slopeb is the y-intercept

Taking the two points from the table

(1, 3)(2, 6)

Determining the slope between (1, 3) and (2, 6)

(x₁, y₁) = (1, 3)

(x₂, y₂) = (2, 6)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [6 - 3] / [2 - 1]

               = 3 / 1  

               = 3

Thus, the slope of the line = m = 3

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the table, it is clear

at x = 0, y = 0

Thus, the y-intercept b = 0

now substituting m = 3 and b = 0 in the slope-intercept form of the line equation

y = mx + b

y = 3x + 0

y = 3x

Therefore, the equation of the line is:

y = 3x

The graph of the line equation y = 3x is also attached.

at her job Jessie earns 9.75 an hour. she also earns a bonus of 80 dollars every month.
Jessie needs to earn at least 500 dollars a month. create an inequality that represents this situation, where h represents the number of hours that Jessie works in a month in order to earn at least 500 dollars

Answers

Answer:

9.75h + 80 ≥ 500

Step-by-step explanation:

Hi! If we look at the problem, it says that "Jessie earns 9.75 an hour." If it is asking you to use h as the hour, it results to 9.75h. Next, she gets a bonus of 80 dollars every month. 9.75h + 80. Lastly, it says she "needs to earn at least 500 dollars". at least is a fancy way of saying greater than or equal to '≥'.

what is a factor for -20?​

Answers

Answer:

1 ,2,4,5,10,-1,-2,-4,-5,-10,20

Answer:

factors are 2 and 5.

Step-by-step explanation:

Factors are numbers which you can multiply together to get another number. For Example : The numbers 2 and 3 are factors of 6 because 2 x 3 = 6. A number can have many factors! Example : 2 and 4 are factors of 8, because 4 x 2 = 8. Also 1 and 8 can also be factors of 8, because 1 x 8 = 8.

on prime factorization, we get the factors of 20 as,

2 x 2 x 5 = 20.

Essentially, to factor a negative number, find all of its positive factors, then duplicate them and write a negative sign in front of the duplicates. For instance, the positive factors of −3 are 1 and 3.

-2 x 2 x 5 = -20

2 x 2 x -5 = -20

(x, y) = (1, -9)

Step-by-step explanation:

y = -9x

-8x-6y = 46

By substituting the value of y (first equation) into the second equation, we get,

-8x - 6*(-9x) = 46

-8x + 54x = 46

46x = 46

x = 1.

So, y = -9

Fact Pattern:Peter Protester is a fairly well-known rabble-rouser. His demonstrations have made news across the southwest, and he's been on TV several times. Now, he has had it with the current state of politics. He gathers his group of followers, and they head to downtown Phoenix to make their grievances known. Peter's followers are generally law-abiding, but there are a few in there who have been arrested after turning peaceful protest into vandalism.After about two hours of chanting and marching, Peter yells, "Alright, we've done the peaceful thing long enough. Now let's take some real action! Let's start breaking some windows now!"Phoenix Police immediately arrest him.Meantime, Rachel Reporter is in the KPHO-TV newsroom and gets a call from a police source. The source tells Rachel to take a look at the police report from Peter's arrest. Rachel heads down to the Phoenix Police Records Department and gets a copy of the police report. In it, the arresting officer writes, "This is the same Peter Protester who was convicted of domestic terrorism in 2010."Rachel believes she has a real scoop on her hands and calls for a live truck to meet her at the scene of the protest. Rachel's live report includes the news of today's arrest. She also quotes the police report, saying Peter was convicted of domestic terrorism in 2010." Rachel did not check with police or try to get ahold of Peter in jail or speak to his lawyer to verify the conviction.As it turns out, the police report was inaccurate. Peter was never convicted of domestic terrorism.What charge would prosecutors likely file against Peter and will the case succeed? why?If Peter sues Rachel, what lawsuit would he likely file and would he succeed? why? Is actual malice required here and is it present? why? Does the fair report privilege apply here to protect Rachel from liability? why? hurry please. Compare and contrast Quebec and Ontario. 12 Points! which of these inferences is the BEST Read this passage from chapter 5 of The Prince.There are, for example, the Spartans and the Romans. The Spartans held Athens and Thebes, establishing there an oligarchy: nevertheless they lost them. The Romans, in order to hold Capua, Carthage, and Numantia, dismantled them, and did not lose them. They wished to hold Greece as the Spartans held it, making it free and permitting its laws, and did not succeed. So to hold it they were compelled to dismantle many cities in the country, for in truth there is no safe way to retain them otherwise than by ruining them. And he who becomes master of a city accustomed to freedom and does not destroy it, may expect to be destroyed by it, for in rebellion it has always the watchword of liberty and its ancient privileges as a rallying point, which neither time nor benefits will ever cause it to forget. And whatever you may do or provide against, they never forget that name or their privileges unless they are disunited or dispersed, but at every chance they immediately rally to them, as Pisa after the hundred years she had been held in bondage by the Florentines.What text evidence supports Machiavellis primary purpose to persuade readers that a conquering prince must destroy a former republic if he hopes to hold it?
