f(x+1) = ((x+1) - 7) / ((x + 1) + 5) = (x -6)/(x + 6)

Hello, career at Wal*mart....

That's what I got. Wouldn't it be -1?

For free?

I'll paypal you like $2.00

Looks good

(x -6)/(x + 6)
If x is 9, then 9-6/9+6 = 3/15 = 1/5
Or if x is 3, then 3-6/3+6 = -3/9 = -1/3

Now I don't know if you're even being serious.

 

[Ness]

The answer is

Spoiler

deez nuts

 

[tater]

(x -6)/(x + 6)
If x is 9, then 9-6/9+6 = 3/15 = 1/5
Or if x is 3, then 3-6/3+6 = -3/9 = -1/3

is the equation simplified to -1? Or is it just (x-6)/(x+6)?

I know everyone is going to roast me for this.

It cannot be simplified any further

 

[tater]

Thanks!

For the f(-5) would it be undefined or zero?

 

[BurnSlow]

Okay...

1). F(x)= (x-7)/(x+5) solve for f(7), f(x+1), f(-5)

I got 0,-1,0

I'm at work so I may be a bit slow to post...

No shyt, you good:

7-7/12 = 0/12 = 0

x-6/x+6 = -1

-12/0 = imaginary numbahs!!!!

This, can't be simplified past that. my bad.

CHECK You throw different numbers in (x-6)/(x+6) and you won't get -1 everytime

You can't simplify it because x is not known.
tater, you need a tutor.

2). The function T given by T(d) = 10d + 20 can be used to determine the temperature T in degrees Celsius, and a depth d in kilometers inside of the earth. Find the temperature T(5), T(20) and T(1000)

70, 220, 10020

I feel like these are too easy...

Or I'm just wrong.

ETA: that initial answer was wrong...

That edit saved you. How you managed to get a negative number is beyond me. If you really need help, I may be of assistance.

A tutor?! I'm broke!

I'll teach myself

I've got an A so far. I just need some clarification...all the time

You are in high school?
