Answer 1

@iGreen

Answer 2

Find the inverse first

Answer 3

\(\sf y = \dfrac{x - 7}{3}\)

Switch 'x' and 'y'

\(\sf x = \dfrac{y - 7}{3}\)

Now solve for 'y'

Answer 4

Can you do that?

Answer 5

Not really sure but is this the inverse? 3y = (x-7)?

Answer 6

We divide 3 to both sides, not multiply, it would actually give us:

\(\sf \dfrac{1}{3}x = x - 7\)

Answer 7

Now add 7 to both sides to complete the inverse

Answer 8

Sorry that's \(\sf \dfrac{1}{3}x = y - 7\)

Answer 9

10y =x?

Answer 10

No, just add 7 to both sides, you can't combine anything.

Answer 11

So 7 + 3y = x?

Answer 12

1/3x*

Answer 13

\(\sf 7 + \dfrac{1}{3}x = y\)

Answer 14

Now plug in 4 for 'x' and solve

Answer 15

So the correct answer would be 19?

Answer 16

No..how did you get that?

Answer 17

Idk I got confused when you said plug in 4 for x and solve I was debating on 19 or 33 but Idk I''m not that good in math : /

Answer 18

I'm

Answer 19

19 is correct

Answer 20

I made a misstake lol

Answer 21

mistake*

Answer 22

Oh yay I was right :D what mistake did you make?

Answer 23

We multiply 3 to both sides, not divide..so it should've been \(\sf y = 3x + 7\), and plugging 4 in gives us 19.

Answer 24

I divided 3 to both sides instead of multiplied, my bad.

Answer 25

Ohhh It's ok But can you check this last question to see if I got it right it's with x and y chart

Answer 52

@twister02 lol!

Answer 53

try multiplying top and bottom by xy

Answer 54

Hmmm hold on

Answer 55

for the numerator you would get
(xy)((1/x) + (1/y)) = (xy)(1/x) + (xy)(1/y) = y + x

and same idea for the denominator (except with a negative in the middle)

Answer 56

:O Interesting I think I know the answer :O

Answer 57

idk

Answer 58

Is it D :O x+y/x-y?

Answer 59

look at the order in the numerator that I got
try again

Answer 60

Awww V_V

Answer 61

I keep getting x+y/x-y : /

Answer 62

\[(\frac{ 1 }{ x } - \frac{1}{y})*(\frac{xy}{1})\]

Answer 63

\[\frac{ xy }{ x } - \frac{xy}{y}\]

Answer 64

Ohhhh
