Answer 1

a) Identify one variable

Any ideas here?

Answer 2

y

Answer 3

coefficient is 4

Answer 4

the other two i dont now

Answer 5

are u there

Answer 6

yeah sorry about that

Answer 7

alright, so you got parts a) and b)

Answer 8

you just need c) and d)

Answer 9

and e)

Answer 10

yes

Answer 11

c) Identify one term

A term is simply a monomial

Any monomial is basically a coefficient multiplied by a variable term

So 4x is one term for example

Answer 12

i think i got e

Answer 13

What did you get for the answer on part e)?

Answer 14

give me a minute am working on it

Answer 15

alright

Answer 16

4x-6x

Answer 17

good, which simplifies to ???

Answer 18

2x

Answer 19

-2x since 4-6 = -2

Answer 20

okay

Answer 21

now what about the y terms?

Answer 22

2y +y

Answer 23

good, which adds to?

Answer 24

3y

Answer 25

good, so overall, the expression simplifies to

-2x+3y

Answer 26

so is going to be
4x-6x=y+2y
-2x=3y

Answer 27

not sure how you're getting that

Answer 28

so how i will do it

Answer 29

lol

Answer 30

you just simply get to the point -2x+3y and you're done

Answer 31

so just put
y+4x+2y-6x
-2x+3y

Answer 32

exactly, that's what you put for part e)

Answer 33

thank so much

Answer 34

and i need help for something else u think u could help me

Answer 35

sure thing, what's your question?

Answer 36

1. Explain how using PEMDAS backwards helps you solve most equations?
2. What does it mean to “isolate the variable” when given an equation?
3. How do formulas help us understand relationships between variables in standardized equations such as area formulas, or the distance-rate-time formula?


1. Given a subset of the following set, all whole numbers greater than 5, explain why each of these numbers are or are not included in this subset: 1, -6, 2/3, 4.5, 10, 176, 189.2, -4.327.

2. Give an example of how sets or Venn diagrams can be used in science, history or language arts.

3. What effect do the words “or” and “and” have on a group of numbers when you are defining sets?

4. Explain the relationship between the domain and range of a function.

Answer 37

which one are you having trouble with?

Answer 38

all of them i dont now nothing

Answer 39

Are you familiar with PEMDAS?

Answer 40

nope

Answer 41

have you heard of the order of operations?

Answer 42

yes

Answer 43

PEMDAS is simply an acronym or device used to remember the order of operations

Answer 44

so how i could explain it

Answer 45

You follow the order of operations to evaluate something like

2*3 + 5

to get

2*3 + 5 = 10


Now say that the '3' is covered up with an 'x' to get


2x + 5 = 10

Answer 46

You can't evaluate the left side any more because you don't know x. So you have to "undo" everything by following the order of operations backwards to find x.

Answer 47

okay but from where u got the x

Answer 48

I just randomly replaced a number with 'x'

Answer 49

okay got it

Answer 50

To make a "known" become an "unknown"

Answer 51

ok got it

Answer 52

how about 2

Answer 53

question 2

Answer 54

2. What does it mean to “isolate the variable” when given an equation?

To isolate anything is to get it by itself, so to isolate a variable, we're getting it to one side and moving everything else to the other side

Answer 55

So we're trying to get it in the form

x = ....

Answer 56

so going to be taking all the number and just staying with the variable

Answer 57

yes

Answer 58

keep the variable on one side, move everything else to the other

Answer 59

okay got it

Answer 60

question 3

Answer 61

i hope am not bodoring u too much

Answer 62

i really appreciated

Answer 63

3. How do formulas help us understand relationships between variables in standardized equations such as area formulas, or the distance-rate-time formula?


Formulas allow us to compute one value if we know another


Ex: if you know the length and width, you can find the area using a formula


Also, we can see how one variable changes as we change other values. This will allow us to do things such as maximize profits or minimize costs.

Answer 64

am sorry i do go

Answer 65

I'm not sure what you mean

Answer 66

i was in the bathroom sorry just came back lol

Answer 67

oh gotcha lol

Answer 68

so we just missing these1. Given a subset of the following set, all whole numbers greater than 5, explain why each of these numbers are or are not included in this subset: 1, -6, 2/3, 4.5, 10, 176, 189.2, -4.327.

2. Give an example of how sets or Venn diagrams can be used in science, history or language arts.

3. What effect do the words “or” and “and” have on a group of numbers when you are defining sets?

4. Explain the relationship between the domain and range of a function.

Answer 69

are u there

Answer 70

yes, did my explanation make sense?

Answer 71

oh yes am right behind u;u are a good teacher

Answer 72

1. Given a subset of the following set, all whole numbers greater than 5, explain why each of these numbers are or are not included in this subset: 1, -6, 2/3, 4.5, 10, 176, 189.2, -4.327.


Is 1 greater than 5?

Answer 73

nope

Answer 74

So that's why 1 is NOT part of the set

Answer 75

is -6 greater than 5?

Answer 76

yes

Answer 77

keep in mind that the 6 is negative

Answer 78

so okay is no is not greater

Answer 79

you got it, so -6 is NOT part of the set

Answer 80

You're doing this for EVERY number listed above

Answer 81

but how i will explain it

Answer 82

1, -6, 2/3, 4.5, 10, 176, 189.2, -4.327.
one is not greater than 5,-6 is not greater than 5,2/3 is not greater than 5,4.5 is not greater than 5,10 is greater than 5,176 is greater than 5,189.2 is greater than 5 and -4.327 is not greater than 5

Answer 83

tell me if am right

Answer 84

are u there

Answer 85

good, you got it, but...

Answer 86

but what

Answer 87

189.2 isn't a whole number and 10 seems like it's missing something...not sure what

Answer 88

so 182.2 is not and 10 is just liked that in the question so is a whole number

Answer 89

i mean 189.2

Answer 90

hmm that's very strange

Answer 91

thats the way the teacher put it

Answer 92

well 10 is a whole number and it's greater than 5, so it shouldn't be excluded...but they want it to be for some reason

Answer 93

so how will i explain it

Answer 94

You'll just have to ask your teacher about it. Maybe there's a typo?

Answer 95

no thats the way the question is

Answer 96

Well then I'm not sure

Answer 97

okey that alright

Answer 98

I'd still ask your teacher about it
