Acomputer printer can print a 900 word document in 12 seconds. at this rate, how many seconds are required to print a document that contains 1200 words?

Hello!

To find how much the computer printer can print word documents per second, we divide the given values, 900 word documents by 12 seconds.

900 word documents / 12 seconds = 75 word documents/second

With that, we can divide 1200 word documents by the 75 word documents/second to find how many seconds are required to print a 1200 word document.

1200 word documents / 75 word documents/seconds = 16 seconds

Therefore, it will take 16 seconds for a computer printer to print a 1200 word document.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
