Hello, 

May I ask where did you get the 25 from ? 

I got -0.04 for the horizontal interecept ? 

Bets and Thank you 

Thank you ! :D 

3,14 = PI 

Thank you for your help, 

I was lost about the both side, I just did it again and got it right ! 

Thank you so much ! I really appreciate ! 

Whoooooo awesome ! 

So basically, I just have in order to draw that to make my onw table and then plug my number in the x value

then I just have to plug the coordinate points into the graph ! 

Perfect, Thank you for your answer ! :)

So Im sorry but Im a bit confused with your answer 

A. would be : 403.4287934927351226,

B . 1 

C. 0.3678794411714423

Right ? 

From what I understand, 

I found : 

A . -40.1711 

B . 11.0230 

C. 403.4270 

Right ? 

Hi, Thanks for you answer, 

However I did not find -15 but onlny 15 for the slope of 100-15x 

How did you find the b : A(t) = 150000 - 300t ?? 

Best, 

Thalys 

I everyone i wonder if you could correct me ? 

in this linear modeling devil work ! 

A(t) = 150000 - 300t 

I did : A(0) = 150000 - 300*0 = 150000

So the vertical interecpt is ( 0,150000) 

Then A(t) = 0      

0 = 150000 - 300t 

Solve for t : 0 = 150000 - 300t ( add t to the both side ) 

300 t = 150000 ( both side isolated by the t ) 

t = 150000 / 300 : 500 

So the horizontal interect is ( 500,0 ) 

 Right ? 

Thank you, 

Best,

I everyone i wonder if you could correct me ? I correct it myself 

in this linear modeling devil work ! 

A(t) = 150000 - 300t 

I did : A(0) = 150000 - 300*0 = 150000

So the vertical interecpt is ( 0,150000) 

Then A(t) = 0      

0 = 150000 - 300t 

Solve for t : 0 = 150000 - 300t ( add t to the both side ) 

300 t = 150000 ( both side isolated by the t ) 

t = 150000 / 300 : 500 

So the horizontal interect is ( 500,0 ) 

 Right ? 

Thank you,

Hi, 

I tried to work on Probleme B as asked by Rom :p 

Here is what I found if someone could correct me ?? 

Vertical Interectp : 150000 - 300* 0 = -150000 so Vertical Intercept = ( 0, -150000) 

Horiztonal Interectp : ( 147000, 0 ) 

Help, I feel like Eveyrthing's wrong :( 

I can graph anything here 

Hi Rom, 

Thank you so much for your answer, and with your help I think I almost get it, 

The thing I have to do, is plug 0 instead of x and solve it 

then plug 0 again instead of y 

Then solve it and it will give me the point of the x and y axes than I have to plug in ? 

I try to do (a) again first, alone to see if I get the same result as you did ! 

And then work on (b) thanks so much, enjoy your day ! 

I get it, thank you for you help ! 

Best, 

Thalys 

Yes, I understand 

But since it is for a Month + 8 days ? 

Do I have to take the 8 days in account ? 

Best, 

Thank you for you answer, then

If the average balance is 417.74, 

If the annual rate is 15.6%, what is the interest on the card for the billing period ? 

It would be : I : P*R*T so It would be 

417.74 * 0.156 * t = 12 ? 

Best, 

Thank you for your answer, I am still confused about it :(
