I give Use multiplication to solve the proportion
1. a/40 = 3/10
2. 6/11 = c/77

a/40=3/10 means you should multiply each side by 40 Divide the denominators by 11 first, then multiply by 7. c/77 = 6/11. => c/7 = 6. => c = 42.

Step-by-step explanation:

Im rlly srry if this isn't helpful, this isn't rlly my strong suit in math

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
