Lily likes to collect records. last year she had 10 records in her collection. now she has 13 records. what is the percent increase of her collection?

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

source:

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

uhhh idk u yolo?
