Answer:

7 -1 6 | -8

7 -5 7 | 1

0 1 -4 | -5

Step-by-step explanation:

Note that there are four columns in this system, representing the variables x, y and z and constants. So the given matrix pattern is appropriate: It has three columns for the coefficients of x, y and z and one column for the constants.

We need only identify the coefficients and transfer them into the appropriate boxes of the matrix pattern.

We get:

7 -1 6 -8

7 -5 7 1

0 1 -4 -5

Lemur [1.5K]

Answer:

Sam's thinking was incorrect.

On number first we have to move 10 units from 0 in positive direction after that negative sign means move in left direction.

But we have 2 negative signs so we need to move 6 units more on positive or right direct as shown below.

Please help me asp I’ll mark as brainliest

Zigmanuir [339]

Answer:

1) Ordered pairs are (9,5), (11,8) , (13,11), (15,14)

2) Ordered pairs are (20,20) ,(16,17), (12,14), (8,11)

3) Ordered pairs are (1,40),(3,22), (7,13), (15,7.5)

Step-by-step explanation:

1) Rule 1: Add 2 starting from 9

Rule 2: Add 3 starting from 5

Sequence 1 is generated using Rule 1 so, it starts with 9 and we add 2 to get the next number.

Sequence 2 is generated using Rule 2 so, it starts with 5 and we add 3 to get the next number.

Sequence 1 Sequence 2 Ordered Pair

9 5 (9,5)

11 8 (11,8)

13 11 (13,11)

15 14 (15,14)

2) Rule 1: Subtract 4 starting from 20

Rule 2: Subtract 3 starting from 20

Sequence 1 is generated using Rule 1 so, it starts with 20 and we subtract 4 to get the next number.

Sequence 2 is generated using Rule 2 so, it starts with 20 and we subtract 3 to get the next number.

Sequence 1 Sequence 2 Ordered Pair

20 20 (20,20)

16 17 (16,17)

12 14 (12,14)

8 11 (8,11)

3) Rule 1: Multiply by 2 then add 1 starting from 1

Rule 2: Divide by 2 then add 4 starting from 40

Sequence 1 is generated using Rule 1 so, it starts with 1 and then we multiply by 2 and then add 2 to get the next number.

Sequence 2 is generated using Rule 2 so, it starts with 40 and then we multiply by 2 and add 2 to get the next number.

Sequence 1 Sequence 2 Ordered Pair

1 40 (1,40)

3 22 (3,22)

7 13 (7,13)

15 7.5 (15,7.5)

Hw 24 area of parallelogram

Papessa [141]

Answer:

<h2>The width, x, of this parallelogram is 16 cm.</h2>

Step-by-step explanation:

In #14, the area of the parallelogram is 528 cm².

This area is also the value of the formula A = L·W:

A = 528 cm² = (33 cm)·W

To determine the width, W, of this parallelogram, we perform the following division:

W = (528 cm²) / (33 cm) = 16 cm

The width, x, of this parallelogram is 16 cm.

The total temperature measured by 4 thermometers was −16 degrees Fahrenheit. What was the average temperature measured by the 4

Lana71 [14]

Answer:

Step-by-step explanation:

Well average means mean so we have to find the mean of the numbers in the data set. Our numbers are -12,12,-4, and finally 4. When we add all of them up we get 0 and we have to divide 0 by the 4 thermoters and your answer is 0. if this is confusing just leave a comment and ill try to explain better
