Apencil manufacturer has a certain tolerance for the actual lengths of the pencils it produces. after the pencils are manufactured, a 1.1 centimeter eraser is added to one end of the pencil. the total length of each pencil must be between 12.9 cm and 13.3 cm. write an inequality representing the possible lengths of the pencils before the erasers have been added, and then find the lengths.

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
