Question

Agebra help please?

f(3) when f(x)=2x+2

y+10=2y+1

Answer 1

If f(x)= f(a), what is x?

Answer 2

I know that one

Answer 3

Hold on I'm trying to post a third equation

Answer 4

Those two are 8 and 9

Answer 5

its not working..lol

Answer 6

ill try to write it out

Answer 7

OK, WILL WAIT

Answer 8

f^-1 (4) (3x-4)/5

Answer 9

im trying to write an equation but the button isnt working

Answer 10

ok. lets sort the first one first. we will deal with thereafter. u will write it in words. f(x) =f(a), what do u think is x?

Answer 11

8?

Answer 12

Wouldn't it be f(3)2x+2 = 6x+2 = 8x?

Answer 13

ok, x=a, f....(a) and then f...(x) , so x = a. what this means is in place of x, put a, now in your first question, a =3, so in place of x , what do u put?

Answer 14

I put a

Answer 15

u must put 3 in place of x,

Answer 16

because its f(3)

Answer 17

I did...that's how I got 8x

Answer 18

f(3)2x+2 = 6x+2 = 8x

Answer 19

I have to find which 2 problems are alike..

Answer 20

ok, if we put 3 IN PLACE OF x, it means NO MORE x, x is out, now there is 3.

Answer 21

i meant 8a

Answer 22

doesnt matter

Answer 23

we have 8..next problem?

Answer 24

So it wil bel 2(3) +2

Answer 25

next pproblem , put LIKE TERMS together,terms with y on their own side

Answer 26

its 9

Answer 27

i need the other one though

Answer 28

I told you I had these 2 solved already

Answer 29

--> f^-1 (4) (3x-4)/5 <--

Answer 30

YEP. 2y-y=10-1, y=9

Answer 31

ok, type it in words

Answer 32

i did

Answer 33

--> f^-1 (4) (3x-4)/5 <--

Answer 34

--> f^-1 (4) (3x-4)/5 <--

Answer 35

--> f^-1 (4) (3x-4)/5 <--

Answer 36

^^^

Answer 37

its weird..the f has a small -1 above it

Answer 38

yes, a power of minus 1 means 1 over......so it means the inverse of the function f. it means 1 divided by that equation

Answer 39

1 over that whole equation, unfortunately the button is not working so i can't tell head from tail.

Answer 40

is it working for you?

Answer 41

The problem is f^-1 (4) (3x-4)/5

3x-4 is the numerator and 5 is the denominator of the fraction.

4 is the function and -1 is the exponent of f

Answer 42

does that help at all?

Answer 43

oh, ok. oh, i see. ha ha ha. u have a funny way of writing when the button z not working! ok, in place of x, we put 4, so that we will have for the NUMERATOR: (3(4)-4)= 12-4=8
DENOMINATOR IS ALWAY 5, so we will have f^(-1) 8/5. this means the inverse of 8/5. if the inverse of 4/3 = 3/4 what is the inverse of 8/5?

Answer 44

@bbbbbbbbbbbbbbbbbb ?

Answer 45

sorry im back

Answer 46
