Find the lowest common denominator of 3/x^3y and 7/xy^4 . a. x3y4 b. x2y3 c. x4y5 d. xy4

The answer is the option A

Step-by-step explanation:

we know that

The  lowest common denominator it is the smallest positive integer that is a multiple of each denominator in the set

In this problem we have

and

so

between

and

the lowest common denominator is equal to

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
