Answer:

option (4) is correct.

the given expression 9x^2y-4x+3y^3x-2y^2  can be written in standard form as 3y^3x+9x^2y-2y^2-4x.

Step-by-step explanation:

The Standard form of writing an equation,  

1) Look at the degree of each term.

2)  You then write each term in order of degree, from highest to lowest, left to right..

3) The expression x^2y has an exponent of 2 on the x and an unwritten exponent of 1 on the y, so this term is to the third degree (2+1). We add the two degrees together because it has two variables.

Consider the given equation,

9x^2y-4x+3y^3x-2y^2

We have to write it in  standard form using the steps stated above,

first we find the degree of each term in the given expression,

The expression x^2y has an exponent of 2 on the x and an unwritten exponent of 1 on the y, so this term is to the third degree (2+1).

The expression y^3x has an exponent of 3 on the y and an unwritten exponent of 1 on the x, so this term is to the third degree (3+1).

So the highest degree in the given expression is  3y^3x

write each term in order of degree, from highest to lowest, left to right.

following this , we can write the expression as,

3y^3x+9x^2y-2y^2-4x

Thus, option (4) is correct.

Can you extend the zero product property to non zero products of numbers? For example, if ab=8, is it always true that a=8 or b=
larisa [96]
That is not always true because think of it as ab=8 that is just like saying (8)(8)=8 which is absolutely false. If anything it can be either a or be equals 8 while the other variable is 1. (1)(8)=8 or (8)(1)=8

For } (x) = 4x+1 and g(x) = x2 -5, find (f/g)(x)
matrenka [14]

Answer:

Step-by-step explanation:

                                                           4x + 1

The quotient   (f/g)(x) is    (f/g)(x) = ---------------

                                                          x^2 - 5

Note that x^2 means "square of x," whereas "x2" is ambiguous.
