What is the slope of a line with points -5,7 and 1,1

KATRIN_1 [288]

Answer

6/-11

Step-by-step explanation:

use the slope formula m= $\frac{y 2-y 1}{x 2-x 1}$

then sub in numbers m= $\frac{7-1}{-5-1}$

now subtract numerator and the denominator

$7-1= 6$ and

$-5-6=-11$ this now looks like $\frac{6}{-11}$

3, 9, 10, 5, 8, 5, 9, 11, 10, 3, 10 Find the mean of the data.

slava [35]

Answer:

7.55

Step-by-step explanation:

An arithmetic mean is the average value of all the data points.

In order to find the average value, you add all the data points then divide the resulting sum by the number of data points there are.

The sum of all data points:

3 + 9 + 10 + 5 + 8 + 5 + 9 + 11 + 10 + 3 + 10 =

The number of data points:

3, 9, 10, 5, 8, 5, 9, 11, 10, 3, 10

1,2,3,4,5,6,7,8,9,10, 11 = 11 data points

Average value/ Mean:

83 / 11 = 7.545454545454 = rounded to 7.55

1. ADEA has vertices D(8,4), E(2, 6), and F(3, 1). What are the vertices of the image after a dilation with a scale factor of 5

lubasha [3.4K]

Answer:

The vertices of the image are D' (40, 20), E' (10, 30), F' (15, 5)

Step-by-step explanation:

If the point (x, y) dilated by a scale factor k using the origin as a center of dilation, then its image is (kx, ky)

Let us use this rule to solve our question

∵ The vertices of ΔDEF are D (8, 4), E (2, 6), and F (3, 1)

∵ ΔDEF dilated by a scale factor 5

∴ k = 5

∵ The origin as the center of dilation

→ That means, multiply the coordinates of every point by 5

∴ D' = (8 × 5, 4 × 5)

∴ D' = (40, 20)

∴ E' = (2 × 5, 6 × 5)

∴ E' = (10, 30)

∴ F' = (3 × 5, 1 × 5)

∴ D' = (15, 5)

∴ The vertices of the image are D' (40, 20), E' (10, 30), F' (15, 5)
