type the equation that shows the relationship between the variables in this chart: x: 1,2,3,4,5 and y: 7,14,21,28,35

Answers

Answer 1
Answer: It seems as though when the x value is multiplied by 7, you result in the y values (ex. 1*7 = 7). So you could say y = 7x.
Answer 2
Answer:

Final answer:

The linear equation that represents the relationship between the variables in the given chart is y = 7x. This is because for every increase of 1 in the x-variable, the y-variable increases by 7, indicating a linear relationship.

Explanation:

The type of equation that shows the relationship between the variables in the chart with x: 1,2,3,4,5 and y: 7,14,21,28,35 is a linear equation. In this case, for every increase of 1 in the x-variable, the y-variable increases by 7. This indicates a direct relationship.

The equation can therefore be presented in the form y = mx + b where 'm' represents the slope of the line (the amount y changes for each unit increase in x), and 'b' represents the y-intercept (the value of y when x = 0).

In this case, the y increases by 7 for each 1 increase in x, therefore m = 7. As the series starts from 7 when x = 1 (not 0), the y-intercept is 0 (since there is no decrease by going back to x = 0), therefore b = 0. This leaves us with the equation y = 7x + 0 which simplifies to y = 7x.

Answers

Answer:

1. 1080°

2. 36°

3. 27 diagonals

4. 140°

5. 7 sides

Step-by-step explanation:

1. The sum S of the interior angles of a polygon is given by;

S = (n-2) x 180°

Where;

n = number of sides of the polygon.

Therefore, to get the sum of the interior angles of a polygon having 8 sides, we substitute n = 8 into equation (i) as follows;

S = (8 - 2) x 180°

S = 6 x 180°

S = 1080°

Therefore, the sum of the interior angles of a polygon having 8 sides is 1080°

2. The sum of interior angles of a polygon is given by;

S = (n - 2) x 180°

For a polygon which is a regular decagon where the number of sides n = 10, the sum is;

S = (10 - 2) x 180°

S = 8 x 180°

S = 1440°

Since the decagon is regular, then each of its interior angles is given by;

1440° / 10

=> 144°

Now, since we know that the sum of the interior angle and exterior angle will give 180°, then;

The exterior angle of a regular decagon is;

180° - 144° = 36°

Therefore, the exterior angle of a regular decagon is 36°

3. The number of diagonals N of a polygon with n sides is given by;

N = (1)/(2) n(n-3)

So, for a nonagon which has 9 sides (i.e n = 9), the number of diagonals is;

N = (1)/(2)*9(9-3)

N = (1)/(2)*9(6)

N = 9(3)

N = 27

Therefore, a nonagon has 27 diagonals.

4. The sum of interior angles of a polygon is given by;

S = (n - 2) x 180°

For a polygon which is a nonagon where the number of sides n = 9, the sum is;

S = (9 - 2) x 180°

S = 7 x 180°

S = 1260°

Since the nonagon is regular, then each of its interior angles is given by;

1260° / 9

=> 140°

Therefore, the measure of each angle (interior angle) of a regular nonagon is 140°

5. The sum of the interior angles of a polygon is given by;

S = (n - 2) x 180°

So if the sum is 900, then to get the number of sides of the polygon, we substitute S = 900 into the equation;

900° = (n - 2) x 180°

Divide through by 180°

5 = (n - 2)

Solve for n;

n = 5 + 2

n = 7

Therefore, the regular polygon has 7 sides.
