the scale factor of the dilation is

The scale factor of the dilation is

Step-by-step explanation:

Given: The image of (6, 9) under a dilation is (4, 6).

In dilation, the scale factor 'k' is the ratio of the coordinate of image to the coordinate of pre-image.

Taking the x coordinates of both image and preimage, we get

Hence, the scale factor of the dilation is

step-by-step explanation:

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
