Me on question 12. my substitute teacher didn't know how to do this problem so i'm asking you kind people to me

we first need to find the interest

6192-6000= interest

192 = interest

principal * interest  rate= interest

6000 * interest rate = 192

divide each side by 6000

interest rate = 192/6000

interest rate = .032

change to a percent (multiply by 100)

interest rate = 3.2 %

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
