lll 67 points a customer buys a cd for $15 and a video game. the customer pays a total of $42.80 for the two items, which includes 7% sales tax. which equation can be used to find x, the cost of the video game before tax? a). 0.7(15+x)=42.80 b).0.07(42.8-15)=x c).1.07(15+x)=42.80 d).1.08(42.8-15)=x

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
