4−6n=60−2n
what is n?

n = -14

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

4 - 6n = 60 - 2n

Step 2: Solve for n

Step 3: Check

Plug in n into the original equation to verify it is a solution.

Here we see that 88 does indeed equal 88.

∴ n = -14 is a solution of the equation.

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
