Answer:

9/7, 1/6, -3, 4/5

Step-by-step explanation:

Use the $gradient =\frac{rise}{run}$ formula to solve this.

4: $gradient = \frac{14-5}{8-1} = \frac{9}{7}$

5: $gradient = \frac{10-9}{2-(-4)} = \frac{1}{6}$

6: $gradient = \frac{-5-4}{6-3} = \frac{-9}{3} = -3$

7: $gradient = \frac{-1-(-5)}{7-2} = \frac{4}{5}$

Consider line segment AB whose endpoints are (1, 4) and (4, 8). If this segment is dilated by a scale factor of 4 centered at th

gulaghasi [49]

Answer:

The length of the new segments A'B' is 20 units ⇒ answer C

Step-by-step explanation:

* Lets revise the dilation

- A dilation is a transformation that changes the size of a figure.

- It can become larger or smaller, but the shape of the figure does

not change.

- The scale factor, measures how much larger or smaller the image

will be

- If the scale factor greater than 1, then the image will be larger

- If the scale factor between 0 and 1, then the image will be smaller

* Lets solve the problem

- line segment AB whose endpoints are (1, 4) and (4, 8) is dilated by

a scale factor of 4 and centered at the origin

∵ The scale factor is 4 and it is greater than 1

- The length of the image of line segment AB will enlarged by the

scale factor 4

∴ A'B' = 4 AB

* Lets find the length of AB by using the rule of the distance

∵ $d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

∵ A = $(x_{1},y_{1})$ and B = $(x_{2},y_{2})$

∵ A = (1 , 4) and B = (4 , 8)

∴ $(x_{1},y_{1})=(1 , 4)$ and $(x_{2},y_{2})=(4 , 8)$

∵ AB = $\sqrt{(4-1)^{2}+(8-4)^{2}}=5$

∴ AB = 5 units

∵ A'B' = 4 AB

∴ A'B' = 4 × 5 = 20

∴ The length of the new segments A'B' is 20 units

Write two integers whose products is negative?

yKpoI14uk [10]

Answer:

Any negative integer and any positive integer.

Like -5 and 3.

Step-by-step explanation:

In multiplication, a positive number and a negative number will result in a negative product.

So, you can use any positive integer and multiply it by any negative integer to get a negative product.

Using the integers I gave:

$-5*3 = -15$
