Answer:

**Answer:**

4 sets.

**Step-by-step explanation:**

We are asked to find the greatest number of sets you can make using 28 pens and 80 pencils.

To solve our given problem, we will find greatest common factor of 28 and 80.

Factors of 28: 1, 2, 4, 7, 14, 28.

Factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.

We can see that the greatest common factor of 28 and 80 is 4, **therefore, you can make at-most 4 sets each having same number of pens and pencils.**

The student union at school has MP3 players pre-loaded with audio and digital books to check out. When the student starts downloading new books at 9:00 am, there are 15 already loaded. When he checks at noon, there are 30 books completely loaded. Assuming that the computer downloads books at a consistent rate, how many complete books will have downloaded at 3:00 pm?Write a function of books downloaded, y, based on time passed, x (in hours), as well as the total number of books that will be completed by 3:00 pm. A y = 10x + 5; 45 complete books B y = 15x + 15; 65 complete books C y = 5x + 15; 45 complete books D y = 15x + 10; 100 complete books

Column A Column B

1.____ 2x + 3y = −9 A.Positive

B.Negative

2._______ y = 3x − 6

3.______

x y

−1 9

0 7

1 5

4.______

x y

2 −8

3 −7

4 −6

Convert to slope-intercept form, y = mx + b.

Subtract 2x to both sides:

Divide 3 to both sides:

Now it's in slope intercept form, y = mx + b where 'm' is the slope. So the slope here is -2/3, which is Negative.

This is already in slope intercept form. So the slope here is 3, which is Positive.

For #3 and #4, take any two points from the table and plug them into the slope formula.

Let's take (0, 7) and (1, 5).

x1 y1 x2 y2

Subtract:

Divide:

So the slope is negative.

For #4, let's take (2, -8) and (3, -7)

x1 y1 x2 y2

Subtract:

Divide:

So the slope is positive.

You just have to add 2+1/4. The answer is D.2 1/4

It's a dude: 2+1/4 = 2 1/4

Set A: {38, 12, 23, 48, 55, 16, 18}

Set B:{44, 13, 24, 12, 56}

has a greater spread because

**Answer: B has greater spread than A.**

**Step-by-step explanation:**

Since we have given that

Set A: {38, 12, 23, 48, 55, 16, 18}

**Range of A = Highest - Lowest **

Range of A = 55 - 12

Range of A = 43

Set B:{44, 13, 24, 12, 56}

**Range of B = Highest - Lowest**

Range of B = 56 - 12

Range of B = 44

Since Range of B is more than range of A.

**Hence, B has greater spread than A.**

-15 + n = -9

inverse operation

- -15 --15

n = -6

-15+n=-9

n=15-9

n=6

So the answer will be 6

n=15-9

n=6

So the answer will be 6
