1. Mrs. Smith paid $9.45 for 3 pounds of ground beef. What is the constant of proportionality that relates the cost in dollars, y, to the number of pounds of ground beef, x? O Not here 3.15 O 3 9.45 CLEAR ALL

ok bro so its gotta be 3.15

Step-by-step explanation:

9.45/3= 3.15 so yea

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
