Question

I need help with algebra ll hmwrk

Answer 1

okay what about it ?what's the statement ?

Answer 2

Find the inverse

Answer 3

f(x) is same as y so replace f(x) with y
\[\huge\rm\color{ReD}{ y}=\frac{ -12-2\color{blue}{x} }{ 3 }\]
to find inverse(f^{-1}(x)) `switch x and y`
\[\huge\rm\color{blue}{ x}=\frac{ -12-2\color{red}{y} }{ 3 }\]
now solve for y

Answer 4

im stuck lol

Answer 5

alright its okay what u got so fr

Answer 6

Hows that lol

Answer 7

i have no idea
what did you type into the calculator ??......

Answer 8

Answer 11

i put the x= one into wolf fram

Answer 12

do you know how to solve that equation for y ?

Answer 13

first we nee to get rid of the denominator at right side
so multiply both sides by 3

Answer 14

substitute y for f(x) then solve x in terms of y then switch x and y and then replace the y with f^-1(x)

Answer 15

yes right so how would you solve x in terms of y ?

Answer 16

\[\huge\rm\color{blue}{ x}=\frac{ -12-2\color{red}{y} }{ 3 }\]
first multiply both sides by 3

Answer 17

ok so 3x-12 or

Answer 18

\[\huge\rm\color{green}{3}·\color{blue}{ x}=\frac{ -12-2\color{red}{y} }{\cancel{ 3} }·\color{green}{\cancel{3}}\]
multiply both sides by 3
at right side 3 cancels out
then u get \[\huge\rm 3x=-12-2y\]
now move the -12 at left side
how would you do that would add ,subtract,multiply or divide 12 both sides ?

Answer 19

multiply

Answer 20

hmm no it's `-12 -2y`
-12 is subtracting with -2y
so you should apply the opposite of `subtraction` which is addition
so add 12 both sides

Answer 21

ok add negative 12 to both or positive

Answer 22

it's negative 12 at right side so what is opposite of negative ?

Answer 23

positive

Answer 24

yes so to cancel out -12 you should add

Answer 25

yea

Answer 26

let me know what you get
