It will take him 7 months for Jamie to run out of money.

A(7) = -15(7) + 105

A(7) = -105 + 105

A(7) = 0.

Sorry but where is the equation?

To do this question, we will need to find the Least common mutiple of 48 and 56.

We can start off by prime factorazation the 48 = 2^4 x 3^1

                                                             and 56 = 2^3x7^1

Now multiplying the highest exponent prime factors to calculate the LCM of 48 and 56.

LCM(48,56) = 2^4 × 3^1 × 7^1
LCM(48,56) = 336

Sorry but when I looked at it, it was locked so I couldn't answer it but thanks for the tip

First, we observe that the graph of y=f(x) consists of line segments, connecting the points (-4, 4), (-1,0), (0,2),  and (4,-4).

So to plot the graph of y=g(x) we can apply the transformation  $(a,b) \to \left( 3a - 1, \frac{b}{2} \right)$ to each of these points, and then connect them. This gives us the points (-13,2), (-4,0), (-1,1), and (11,-2).  

 Hope this helps! 

I got it working.

Ok, if i can get the diagram working, I might be able to answer the questions.

This link might help a bit

Sorry about that but thank you for letting me know. 

Sorry that I can't do the problems (a) and (c) because the LaTeX code is too complicated for drawing the diagram. I hope you understand

Check this link if the answer is right.

Hope this link helps!

(b): 

Take a point (a,b)  on the graph of y=f(x), so b=f(a). Since $\left( 3a - 1, \frac{b}{2} \right)$ lies on the graph of y=g(x) we have that $\frac{b}{2} = g(3a - 1).$

Substituting b=f(a) we get $\frac{f(a)}{2} = g(3a - 1).$

In order to express g(x) in terms of f(x) we can let x = 3a-1 Then a=$\frac{x + 1}{3}$, so

                                                       $g(x) = \frac{f(a)}{2} = \frac{1}{2} f \left( \frac{x + 1}{3} \right).$

We can start with cases

Case 1: How many of the one digit numbers have the digit 1? We easily know that there is only 1

Case 2: How many of the digit one is written from 10-19? We count that there are 10 digit ones in the first digit and one digit in the last digit. This gives us 11 digit 1 written.

Case 3: How many of the digit one is written from 20-49. There is only three which is 21, 31, and 41.

This gives us the total of 15 digit one written.

Hope this helped! 

Sorry but we need more clue to this or a question in order to solve this question. Do you mean in terms of "y"?
