A photographer enlarged a picture. If the width of the image is 5 inches and the width of the pre-image was x, what is the scale factor for the dilation in terms of x?

To find the scale factor for the dilation in terms of x, we need to compare the width of the image after enlargement to the width of the pre-image.

Let's denote the scale factor as k.

According to the information provided, the width of the image after enlargement is 5 inches. Therefore, we can express this relationship using the scale factor as follows:

Width of image = k * Width of pre-image

Substituting the given values:

5 inches = k * x

Now we can solve for k by dividing both sides of the equation by x:

k = 5 inches / x

Thus, the scale factor for the dilation in terms of x is 5 inches divided by x.

you dumb

I have no idea

5/x

the enlargement ratio is newsize / oldsize
