3. Determine whether these two lines are parallel, perpendicular, or neither. 1 point
8x + y = 7, 4x + 3y = 12 *
parallel,
perpendicular or
neither

Answers

Answer:

The two lines are neither

Step-by-step explanation:

Parallel lines have equal slopes and different y-interceptsPerpendicular lines have a product of their slopes = -1The slope of a line whose equation is ax + by = c is m = [tex]\frac{-a}{b}[/tex]

∵ The equations of the lines are

8x + y = 7 ⇒ 1st4x + 3y = 12 ⇒ 2nd

∵ In the 1st equation a = 8 and b = 1

∴ m1 = [tex]\frac{-8}{1}[/tex] = -8

∴ The slope of the 1st line is -8

∵ In the 2nd equation a = 4 and b = 3

∴ m2 = [tex]\frac{-4}{3}[/tex]

∴ The slope of the 2nd line is [tex]\frac{-4}{3}[/tex]

→ By using the facts above

∵ m1 ≠ m2

∴ The two lines are not parallel

∵ m1 × m2 = -8 × [tex]\frac{-4}{3}[/tex] = [tex]\frac{32}{3}[/tex]

∴ m1 × m2 ≠ -1

∴ The two lines are not perpendicular

∴ The two lines are neither parallel nor perpendicular

Graph: y-3=1/2(x+2)

Answers

Answer:

Step-by-step explanation:

First you need to find the Slope Intercept form or find the point and slope.

The point is: (-2,3)

and the slope is: 1/2

y - 3 = 1/2(x + 2)

y - 3 = 1/2x + 1

y = 1/2x + 1 + 3

y = 1/2x + 4

Slope intercept form: y = 1/2x + 4

Write the equation of the line that goes through (-3.9, -1.4) and is PERPENDICULAR to 6x + 2y = 9

Answers

9514 1404 393

Answer:

10x -30y = 3

Step-by-step explanation:

In general form, you can start by swapping the x- and y-coefficients, negating one of them. To find the new constant for the equation, substitute the values for the given point

2x -6y = 2(-3.9) -6(-1.4)

2x -6y = 0.6

Multiplying by 5 will make the numbers be integers, so will put the equation in standard form.

10x -30y = 3

If the cyclist rides at 10mph and 1mph=1.6kph then 1.6x10=16 which means he was traveling at 16 kilometers per hour and after five hours he would have traveled 80 kilometers

Pls Show your work on the slope

Answers

Answer:

1) slope = 1/5

x - intercept = (10, 0)

y - intercept = (0,-2)

2) use the method I used for number one to do number 2.

Step-by-step explanation:

slope = rise/run = y2-y1/x2-x1

use any 2 points on a line. Chose one y-value which is y2 and the corresponding x-coordinate is x2. In the other coordinates, the y-value is y1 and the x-value is x1. Let's use points:

(-10, -4)

(-5, -3)

y2 = -3, which means:

y1 = -4

x1 = -10

x2 = -5

plug in the values:

-3-(-4)/-5-(-10)

=1/5

X - intercept is when y = 0. Plug in 0 for y when you see it.

x-0 = 10

x=10

x-intercept = (10,0)

Same for y intercept, except x = 0 this time.

0-5y=10

-5y=10

y=-2

y-intercept = (0,-2)

What is the probability of being born in May or on the 30th of any month?

Answers

Answer: 41/365

Step-by-step explanation:

The probability of being born in May is 31/365 (May has 31 days and there are 365 days in a year).

The probability of being born on the 30th of the month is 11/365 (11 months have at least 30 days). However, since we have included May 30 in our MAy probability, we need to use the probability of 10/365.

Add the two probabilities together, and the probability of being born in May or on the 30th is 31/365 + 10/365 = 41/365.

HELP PLS GUY. 15 POINTSIts due by midnight What does the notation STAY SAFE EVERYONE 89 brainly points for this!The phrase miles per hour is an example of a rate of change. What other rates of change commonly used in everyday speech can you think of? In the Short Story "The Necklace" by Guy De Maupassant is about a young woman who fantasizes about wealth, status, and luxury. She is unhappy with her life and wishes she married a man of a greater class than the husband she already has. When she is allowed to appear to the world as if she is of a higher class she is then given a beautiful necklace by her friend who appears to have more than her. She gets carried away during that night and when it is finally time for her to end her marvelous night the necklace is nowhere to be found. She then spends 10 long years paying back for the lost necklace but is told that the necklace was fake all along. The lesson that was to be learned was that Be satisfied and grateful for the things you have rather than striving for things that may appear better but often are also deprived of happiness themselves. Madame Loisel wasnt grateful for the things that she had and continued to strive for things out of reach, through all this she did not open her eyes to see that not everyone was doing as well as she thought, which eventually led to a long period of despair. According to the text Oh, my poor Mathilde! Why, my necklace was paste. It was worth at most five hundred francs!. Her rich friend allowed her to borrow a necklace of diamonds, little did she know that the whole time the necklace was fake. She prejudged her friend and didn't get to know her therefore karma came back to bite her. She prejudged her friend and didn't get to know her therefore karma came back to bite her. If she had eaten her pride, jealousy, and judgment then she would have had the strength to confront her, but for ten long years, she paid way over for something that had no value at all. In Conclusion, I believe that because Madame Loisel constantly strived to move up in the social class, she did not notice that some of her friends that might have appeared to be richer and have nice things just appreciate what they have. And because of this, she ended up wasting a large portion of her life on something pointless. In the story, Madame Loisel explains how she does not want to ask her friend for things because it makes her feel low compared to her. However, when given all the franks saved up by her husband it was simply not enough for her. His best efforts were not good enough which forced her to cowardly confront her friend to borrow some jewels in her possession. Even when her friend offered many different necklaces to her she was still not satisfied and chose the one that looked the most expensive which in the end because of her prejudgment she spent 10 long years paying her back. In the end, because Madame Loisel constantly strived to move up the social class and in doing so when she finally got the chance it didn't end up as a happily ever after. Through this event, we can learn that in life you have to be grateful for everything you can have and achieve. Please help!Need answer fast!
