The coordinates of △abc△abc are a(12,8), b(10,18), c(4,16)a(12,8), b(10,18), c(4,16). after a dilation, the coordinates are a'(6,4), b'(5,9), c'(2,8)a′(6,4), b′(5,9), c′(2,8). find the scale factor.

Step-by-step explanation:

The dilation is a transformation which makes similar shapes.

We know that In two similar geometric figures, the ratio of their corresponding corresponding x-coordinate is known as the scale factor.

For the given situation, the x-coordinate of A in pre-image = 12

The x-coordinate of A' in image = 6

Then , the scale factor for the dilation is given by :-

Hence, the scale factor =

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
