Solve the equation 7 (x-2)= 42

x=8

Step-by-step explanation:

8-2=6

8x7=42

(checked)

8

Step-by-step explanation:

7 is first multiplied into both sides of the parentheses

7x-14=42

then you add 14 to both sides to get rid of the 14 on the left side

7x-14=42

+14     +14

7x=56

then u divide 7x by both sides

7x/7=56/7

x=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
