How do u find the scale factor of dilation

Step-by-step explanation:

We need to understand what is dilation?

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

• A dilation that creates a larger image is called an enlargement. and its scale factor is greater than 1

• A dilation that creates a smaller image is called a reduction. and its scale factor is smaller than 1

To find the scale factor of dilation, we need to identify the coordinates of one point in the original shape and the coordinates of one point in the scaled shape. Then divide the x-coordinate of the scaled point by the x-coordinate of the original point.

For example:

=> the the scale factor of dilation = 2 / 1 = 2

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
