Solve 3(x-2)< 18
a) x< 8
b) x> 8
c) x< -8
d) x> -8

a

Step-by-step explanation:

given

3(x - 2) < 18 ← distribute the left side

3x - 6 < 18 ( add 6 to both sides )

3x < 24 ( divide both sides by 3 )

x < 8 → a

step-by-step explanation:

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
