Question

identify the coefficient and factors of the term
3xy
7

Answer 1

efficient = variable

co = with

co efficient

x BY ITSELF HAS 1 AS COEFFICIENT

( 1 ) x

1 * x = x

examples

5 x
co efficient = 5
if given

2
no efficient
therefore no co efficient






another example
if x = 2

Evaluate

5 x
plug in 2 for the efficient

5 ( 2 )

= 10

Answer 2

why isnt the 2 coe.?
i dont get it :(

Answer 3

example

19x
what is the coefficient

Answer 4

efficient = variable

Answer 5

x?

Answer 6

hmmm
19x

19 x
^ ^
| |
| efficient = variable
|
co efficient = with the variable (co , with)

Answer 7

so 19x is the coe right??

Answer 8

u see where the arrows are pointing
there are 2 parts to it

Answer 9

okay im starting to get it a little

Answer 10

19 x
^ ^
| Efficient = variable- unknown value unless there is a given value to it
| |
| |
co efficient ( with the variable) precedes the variable |
|
|
in which case in example x is given a value

x=2
evaluate
19x
19(2)
= 38

Answer 11

whats wrong now

Answer 12

no i dont :(

Answer 13

hero help me

Answer 14

a variable is just an unknown

Answer 15

(19) (x)

pronounced "nineteen" " ex"

first number is

19

second number

x

these are 2 numbers

you know what

the first number is

19 ( x )
^
1

second number


you do not know the value

it is just x

19 ( x )
^
2

if you do not know the value and it is given a letter such as a, b c, x y z etc.
it is the variable

Answer 16

for

something like this

x

1 ( x ) = x

1 is the co efficient of

1 ( x )
^
1
coefficient

1 ( x )
^
efficient =variable

Answer 17

the coefficient is the number in front of the variable...if there is no number than the coefficient is 1

Answer 18

then*

Answer 19

okay :)

Answer 20

example #1:\[7x~~~\implies~~~\text{coefficient=7}\]example #2:\[y^2~~~\implies~~~\text{coefficient=1}\]

Answer 21

on example 2 where did the 1 come frm?

Answer 22

did you read what i wrote before

Answer 23

"if there is no number then the coefficient is 1"

Answer 24

oops sorry i got it :)

Answer 25

i had to refresh

Answer 26

no problem

Answer 27

so on the problem i have the coefficient is 3/7 ?right

Answer 28

is your problem: \({\large{3\over7}}xy\)?

Answer 29

thats the same thing...yes the coefficient is \(\large{3\over7}\)

Answer 30

okay thanks :)
