Step-by-step explanation:

the solutions should be x≥ -4 or x ≤6

and the right answer is :

3x + 14≥ 2

3x ≥ -12

x≥ -4

1-x ≥ -5

-x ≥ -6

x ≤ 6

Use elimination to solve each system of equations. 1/3x-y=-1 and 1/5x-2/5y=-1
Yakvenalex [24]

Answer:

x=−9 and y=−2

Step-by-step explanation:

Multiply the first equation by 2,and multiply the second equation by -5.

2(1/3x−y=−1)

−5(1/5x−2/5y=−1)

Becomes: 2/3x−2y=−2

−x+2y=5

Add these equations to eliminate y:

−1/3  x=3

Then solve −1/3x=3 for x:

−1/3x        3

−1/3    = −1/3

(Divide both sides by (-1)/3)

x=−9

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

1/3x−y=−1

Substitute−9 for x in 1/3x−y=−1:

1/3(−9)−y=−1

−y−3=−1(Simplify both sides of the equation)

−y−3+3=−1+3(Add 3 to both sides)

−y=2

−y

−1=

2

−1

(Divide both sides by -1)

y=−2

Magdeline wants to know if the number of words on a page in her art book is generally more than the number of words on a page in
Tanya [424]

Answer:

Step-by-step explanation:

To know on  which book, number of words is more between, Computer Science and Math

Magdeline selects 25 pages from each book, then Calculates Mean, Median, Mean Absolute Deviation of number of words on each page.

Book                Mean    Median     Mean Absolute Deviation

Computer science 48.7            40                   9.4

Math                  34.2         45                      1.9

Observing what Magdeline has Done,

Mean is Sum of words on each page of 25 pages divided by 25.

1. Mean of Computer Science book is more than mean number of words on pages of math book.

2.And, Median means , computer science book has more pages which contains 40 words ,and Math book  has more pages which contain 45 words.

3.Now,Coming to Mean Absolute Deviation, which measures the Variability from Mean.

In computer science book ,there is more Variability that is, 9.4 and 1.9 in math book.

So, just by claiming, that because the mean number of words on each page in the computer science book is greater than the mean number of words on each page in the math book, the computer science book has more words per page appears invalid Inference, because variability from mean in computer science book is more than variability from mean in Math book because Mean Absolute Deviation measures Variability fro mean.

Option D:  No, because there is a lot of variability in the computer science book data
