Write an equation in slope intercept form for the line with slope - 3/4 and y-intercept -2. Then graph the line.
​

Answers

Answer:

y = (-3/4)x - 2

Step-by-step explanation:

Start with the slope-intercept form y = mx + b.  Replace m with -3/4 and y with -2.  We then have y = (-3/4)x - 2.

Graphing this line:  Knowing that b = -2, plot the point (0, -2).  Find the x-intercept by letting y = 0 in the above equation and solving for x:

0 = (-3/4)x - 2, or (3/4)x = -2, or x = (4/3)(-2), or x = -8/3.  Plot this x-intercept (-8/3, 0).  Finally, draw a line through the points (0, -2) and (-8/3, 0).

x = 9/2x = 5

Step-by-step explanation:

1. Substitute for k(x) and solve.

  k(x) = 6x -12

  15 = 6x -12 . . . . substitute for k(x)

  27 = 6x . . . . . . add 12

  27/6 = x = 9/2 = 4 1/2 . . . . . divide by 6

2. Find f(x) = 7 on the vertical scale. Follow that horizontal line over to the graph. Follow the vertical line at that intersection down to the x-axis. It will be halfway between the lines marked 4 and 6. That is, the x-value is 5.

  f(x) = 7 = f(5)

  x = 5

Seven values are 3, 3, 3, 4, 5, 8 and x.
The mean of these seven values is equal to twice their mode.
Calculate the value of x.

Carla reads 36 pages in 3 hours. At this
rate, how long will it take Carla to read a
book with 180 pages?

Answers

180/36 is 5 so 5 times 3=15

Answer:

It will take 15 hours to read a book with 180 pages

Step-by-step explanation:

First, let's set up a ratio to find how many pages she reads per hour:

36:3 = 12:1

Now we can set up fractions to solve:

[tex]\frac{12}{1} =\frac{180}{x}[/tex]

Cross multiply:

[tex]12x=180[/tex]

Divide each side by 12:

Now the question were really asking here is "475.19 is 79% of what?"

475.19 = 0.79 * x

You'll have to expand the picture to read what it says. Question 1: In " The Next Adventure, " how does Malik change from time he finds out he's moving to Japan to the end of the story? Use specific details and evidence from the text to support your response. Should be one or two complete paragraphs. ( Will Mark Brainliest and only please be 100% correct and honest with your response and you'll get Brainliest . Thank you . ( Read the first two paragraphs here -----------> Malik had only a week's notice when his mother's transfer to the Kaden Air Base in Okinawa, Japan, came through. He wasn't sure if she had been given only a week's notice, or if she'd just waited so long to tell him because she suspected that he would not take it well. As it happened, he didn't take it well. He reminded her heartedly about his best friend Jamie's sixteenth birthday party that was still a month away, and his own upcoming eligibility to acquire his driver's license that summer. She had promised to take him for the test if he completed the driving safety course, which he had paid for just last week. But it didn't matter what he said, because the professional movers were already there. and his mother wore the expression that told Malik he didn't have the slightest chance, and that she was very busy with other matters. The first week in Japan was predictably atrocious. Malik's mother came home ever night with infuriating new suggestions for how he could spend his time ----or, as he preferred to think of it, how he could pass his sentence. They wouldn't be there forever. She encouraged him to visit the skate park and the jogging trails like he used to do at home, or that he meet the other kids his age at the pool before the weather closed it down. He didn't want to know the others any more than he wanted to settle down in Okinawa, two million miles from where he belonged. He preferred to spend his time browsing social media and trading complaints with Jamie. He and Jamie had been friends for their entire lives, which was a foreign concept to most of the base kids Malik talked to when his mother did manage to get him to interact. Whenever he brought it up, they all launched into a game where they named the place they'd stayed the longest, and he felt like the outsider he knew he was.
