Suppose that X is a vertical segment that lies on the y-axis with its beginning at origin and ending at the point (0,4). Then the length of this segment is 4 units.
If you vertically compress this segment by factor of 1/4 with the centre of compression at the origin, you recieve a segment that also lies on the y-axis with its beginning at origin and ending at the point (0,1) (the length of this image segment is 1 unit).
So, the question is: if a segment that lies on the y-axis with its beginning at origin and ending at the point (0,4) is vertically compressed <span>by factor of 1/4 with the centre of compression at the origin, what is the image of this transformation?

A magazine has 5,580,000 subscribers this year. This number is down 7% from last year. How many subscribers were there last year

cestrela7 [59]

I got the answer C. This was by multiplying .07 (the decrease) by 5,580,000. Which I then got the number 390,600, which I added to 5,580,000.
