Pam has 2 jobs. at one job she makes $8 per hour. at the second job she makes $12 per hour. one week she worked 30 hours and made $268. how many hours did she spend at each job?

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

after simplifying it i got: -36.25 as my answer. hope that !
