please help (IN A HURRY)

Answer 1

@ganeshie8 @mathstudent55 @jdoe0001

Answer 2

first plug in -6 for the x values in the function of g(x)

Answer 3

then simplify that
then plug in what you got into the x values in the function of f(x)

Answer 4

:o

Answer 5

get it?

Answer 6

how to i plug in the -6 in the fraction

Answer 7

do*

Answer 8

\[\frac{ 1 }{ 2x-2 } \rightarrow \frac{ 1 }{ 2(-6)-2 } \rightarrow \frac{ 1 }{ -12-2 } \rightarrow \frac{ 1 }{ -14 }\]

Answer 9

ok so i got -10 on the left side and 1 over -14 on the right side what do i do next

Answer 10

no, f(g(-6)) means to plug in -6 into the function of g(x) and take what you got from that, and plug that into the function of f(x)

Answer 11

so you plug in 1 over -14 into f(x)

Answer 12

this is confusing @jigglypuff314

Answer 13

g(-6) means to plug in -6 into the function of g(x)
f (g(-6)) means to plug in what g(-6) equals into the function of f(x)

Answer 14

>.< can you please like write out the problem for me step by step

Answer 15

\[g(x) = \frac{ 1 }{ 2x-2 } \rightarrow g(-6)=\frac{ 1 }{ 2(-6)-2 }\] do you understand this so far?

Answer 16

yes

Answer 17

you plugged in the -6

Answer 18

then you simplify that

Answer 19

do i multiply 2 and negative 6

Answer 20

yes

Answer 21

and then - 12-2

Answer 22

is it 1 over negative 14

Answer 23

yes :)

Answer 24

thats it?

Answer 25

then you plug 1 over 14 into x-4

Answer 26

how do i do that

Answer 27

so 1/14 - 4

Answer 28

14-4

Answer 29

no, (1 over -14) - 4

Answer 30

i multiply - 4

Answer 31

no, 4 = 56 over 14
so 1 over negative 14 minus 56 over 14

Answer 32

ho do i solve that

Answer 33

55over -28

Answer 34

no, negative number minus number equals negative added numbers
and when adding fractions (or numbers over numbers) you don't add the bottom two numbers.

Answer 35

so 55 over 14?

Answer 36

-1-56 = -57
so your answer is negative 57 over 14

Answer 37

thats not right

Answer 38

how is it not?

Answer 39

my choices are 9

3
