Acarpenter has
at most $250 to spend on lumber. the inequality
8x + 12y = 250 represents the numbers x of 2-by-8
boards and the numbers y of 4-by-4 boards the
carpenter can buy. can the carpenter buy twelve
2-by-8 boards and fourteen 4-by-4 boards? explain.

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

the first one, all those points on the line just make a strait line.

no one knows lol
