What is the GCF of the expression 6(x^3)(y^3)+45(x^2)(y^2)+21xy? *

Your answer

3xy

Step-by-step explanation:

We are to determine the GCF of the expression.

THe GCF of the expression is the term that exactly divides all the terms in the expression

Step 1

If we observe the expression carefully, we notice that it has a common term of 3, x and y. That is, 3,x and y divides each term.

Step 2

Divide by 3xy for confirmation

Therefore, we can confirm that the GCF is 3xy.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
