Pll i am timed 1. name the property illustrated (8+6)+4=8+(6+4) (a) opposite of a sum property (b) associative property of addition (c) commutative property of addition 2. name the property illustrated +6)=3+(-6) (a) opposite of a sum property (b) associative property of addition (c) commutative property of addition 3. name the property illustrated -8+(14)= 14 +(-8) (a) opposite of a sum property (b) associative property of addition (c) commutative property of addition

Correct answer for 1. is (b), for 2. is (a) and for 3. is (c) !

Good luck!!!

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
