Answer:

(6,1), (8,8), (12,22), (20,50)

Step-by-step explanation:

The required sequence of ordered pairs is (6, 1), (8, 8), (12, 22), (20, 50). Option D is correct.

The first rule is to multiply by 2, then subtract 4 starting from 6. The second rule is to add 3, then multiply by 2 starting from 1. What are the first four ordered pairs using the two sequences to be determined?

In mathematics, it deals with numbers of operations according to the statements.

Let the number be x for the first sequence and y for the second sequence.
The first rule is to multiply by 2, then subtract 4 starting from 6.

= 2x - 4
the sequence can be given as
6 is the first number
next number = 2(6) - 4
                     = 12-4
                     =  8
So the next term is 8. Similarly next 2 terms can be given as 12 and 20
Values of x = 6, 8, 12, 20

Now, the second rule is to add 3, then multiply by 2 starting from 1.

= (y + 3)2
First term = 1
Next term = (1 + 3)2
                =  8
Similarly, the next two terms can be obtained.
y = 1, 8, 22, 50

Thus, the ordered pair can be formed as (6, 1), (8, 8), (12, 22), (20, 50).

#SPJ2

Answer:

-5

Step-by-step explanation:

Recall that slope = rise/run.

Here the change in y (the rise) is -10 (y changes from +12 to +2), and the  change in x (the run) is 2, since x increases from 3 to 5).

The slope of the line through these points is m = rise / run = -10/2 = -5

Answer:

for the second one x = 34

Step-by-step explanation:

x + 23 = 57

subtract 23 on both sides

x + 23 - 23 = 57 - 23

x = 34

7*8=$56

Step-by-step explanation:

It is 7 people because they all pay $8 so her and her 6 friends equals 7. Then 7 times $8 is $56

Answer: 1,2,and 4. I did it online and got it right!

Answer:

B. 15 square meters (for the triangles)

D. 25 square meters (for the square base)

Bonus: The total surface area would be 85 square meters.

Step-by-step explanation:

The square base is easier to deduce here; simply square 5 to get 25 square meters for the base.

The triangles require some math, however. But it is relatively simple

(5 * 6)/2

30/2

15 square meters for the triangles.

For bonus, I'll find the total surface area.

5² + 4((5 * 6)/2)

First, square 5 to get 25.

25 + 4((5 * 6)/2)

Now multiply 5 * 6 to get 30.

25 + 4(30/2)

Then divide 30 by 2 to get 15.

25 + 4(15)

Now multiply 4 by 15 to get 60.

25 + 60

Lastly, add 25 and 60 to get 85.

The entire square pyramid's surface area is 85 square meters.

Answer:

y = 6z - 5

Step-by-step explanation:

Start with the given function y = 2x -5.  Substitute the given 3z for x:

y = 2(3z) -5

Simplify this through multiplication:

y = 6z - 5

Answer:

Step-by-step explanation: First, you need to write all your data down from least to greatest. Next, count up all the numbers to see how many students. Then you want to find the mean which is average (add then divide). Median is the middle so you will x each number out till you get to the middle, and if the middle is 2 numbers, you find the average of them to find the median. Mode means most often. Range is highest minus lowest. And you can do the next 2.

Answer:

Range: 7

Greater than 9 is: 7

I'm not really sure about the distribution

Total Student: 25

Mean: 8.68

Median: 9

Mode: 8

Answer:

multiply 7.5 by 4

Step-by-step explanation:

múltiply 7.5 by 4

Answer:

1.5*4 = 6

Step-by-step explanation:

Since side length "IH" dilated to "BA" by the scale factor of 4, the same patter would be followed to dilate "HJ" to "AC", so you have to multiply side length 1.5 (HJ) by the scale factor of 4 to get "AC".

Answer: 1300 cm^3, 850 cm^2

Step-by-step explanation:

With a triangular prism, you need to calculate the surface area of the triangle first and then the length. Here's how to solve for the volume (A):

Triangles is b*h/2, plug in the equation

10*13/2

130/2

65

Now use the length of the rest of the shape, which is 20 cm.

65*20=1300

the volume is 1300 cm^3.

for B, finding the surface area requires you to analyze each individual part of the shape.

Each part colored in represents a different shape:

Red:

10*20=200

Blue:

13*10/2=65

65*2=130 (Two triangles)

Green:

13*20=260

260*2=520 (Two rectangles)

Add them all up together.

200+130+520= 850 cm^2
