If 3r + 2s = r - 8, then r + s =

r + s = -4

Step-by-step explanation:

3r + 2s = r - 8

3r + 2s - r = -8

2r + 2s = -8

r + s = -8/2

r + s = -4

8 apples are left.

step-by-step explanation:

10-2=8

10 apples

take 2

now u have 8

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
