A maintenance company charges an office owner $1,800 to clean 5 of his machines. How many should he charge to fix 3 machines?

$1080

Step-by-step explanation:

Take 1800 and put it over 5, like a fraction and solve to make the denominator 1. Then multiply by three because we are looking for the cost of 3 machines

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
