ill help

Answer 6

please

Answer 7

holdon

Answer 8

ok

Answer 9

let me know when u get the answer

Answer 10

i dont have it

@DanJS

Answer 14

k

Answer 15

do you remember when you answered this question for someone else?

Answer 16

i think for the decending order, put the highest powers of x first

Answer 17

descending is when the exponents decrease, from greatest to least.

Answer 18

i know +1 is at the end, correct? because it has 0

Answer 19

The degree is the highest exponent, therefore is the degree 5? or is '5' all of them added up?

Answer 20

nah i cant remember

3x2y + 4xy + 1 – 5x4y – 6y

i thought the standard term order in these with x and y started with the highest power of x , then y, but if it is just the decending term order, then yeah the total of x and y powers first

Answer 21

im so lost if you copy and paste the problem into google it pops up the one that you did... maybe if i send you the link and you look back at it you could remember?

Answer 22

theres this one that isnt yours. http://openstudy.com/study#/updates/55cea025e4b0c5fe98060b1a

Answer 23

http://openstudy.com/study#/updates/55c3cea7e4b0f6bb86c3bd70 this one IS yours

Answer 24

is the first one written in descending order?

Answer 25

yeah i always remembered to put the highest x term first, then the y term if no x left

so for the order,
3x2y + 4xy + 1 – 5x4y – 6y

-5x^4*y + 3x^2*y + 4*x*y - 6y + 1

Answer 26

prioritize the x power, then terms in only y. then constant

Answer 27

the math is unchanged either way , it is just the convention people agree to list things

Answer 28

c. is 5

Answer 29

that is for sure, right?

Answer 30

A.The polynomial in descending order is −5x4y+3x2y+4xy−6y+1 ???

Answer 31

yeah decending order of the terms, look at the x's first, put those in decending order, then next the terms in only y in decending order

Answer 32

so C &A are right?

Answer 33

yaeh, the degree is the largest combined powers 5

Answer 34

what is B?

Answer 35

each term is a monomial , A*x^n*y^m, the total number of them is 5

Answer 36

I Dont get it

Answer 37

a constant value 1 is also 1*x^0*y^0

Answer 38

number of things added or subtracted together

Answer 39

no idea lol

Answer 40

-5x^4*y
+ 3x^2*y
+ 4*x*y
- 6y
+ 1

5 terms

Answer 41

A.The polynomial in descending order is −5x4y+3x2y+4xy−6y+1
B. The polynomial by the numbers of terms is 5
C. The degree of the polynomial is 5.

Answer 42

is that correct?

Answer 43

yes

Answer 44

Let f(x) = 3x2 – x + 2 and g(x) = 5x2 – 1. Find f(g(x)). Show each step of your work.


do you know this?

Answer 45

yeah, it is two functions compunded or chained together

f(x) = 3x^2 - x + 2
means whatever you decide to make x, the function will apply that rule to it and give back the result.

Answer 46

f(input) = output

so for the f( g(x) ) , the input of f is g(x)

Answer 47

f(x) = 3x2 – x + 2 and g(x) = 5x2 – 1

f ( g(x) ) = f( 5x^2 - 1)

Answer 48

f ( g(x) ) = f( 5x^2 - 1) = 3*( 5x^2 - 1 )^2 - (5x^2 - 1) + 2
