The simplified form of the expression (5.23x + 3.76) − (3.67x − 6.39) is

Step-by-step explanation:

Consider the given expression is

We need to find the simplified form of the given expression.

Using distributive property we get

On combining like terms we get

Therefore, the simplified form of the given expression is .

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
