A certain lawnmower uses 5 tanks of gas to cut 18 acres of lawn. How many acres could be cut using 8 tanks of gas

28.8 acres

Step-by-step explanation:

18/5 = 3.6, which means that every tank of gas can cut 3.6 acres of lawn. 3.6*8 = 28.8 acres.

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
