I think the answer may be 54 but i'm not sure.
Answer:
A
Step-by-step explanation:
the function f(x) is a straight line. The "-4" means that the graph moves down 4 units. Point A is at y=-4, so this is the point. You can graph the equation and you'll see that it hits point A.
Answer:
£ 21552.13
Step-by-step explanation:
P= £18790
r =4.9% = 
t = 3 years
I = Prt
I = 18790 * 0.049 * 3
=£ 2762.13
After 3 years , the amount in Dan's account = 18790 + 2762.13
= £ 21552.13
To construct the equations for these lines, we are going to use the point-slope formula, which is:

is the slope of the line
is a point on the line
1)
In this case, our point is (2, -1) and our line has a slope of 5. (Remember that the line is parallel, meaning that it has the same slope as the given line. Since the line is in the y = mx + b format, we could easily pick out the slope m as being 5.)
Thus, we can "plug in" what we know into our formula to find the equation of our line:



2)
We are going to do the same thing, except our point is now (0, -5) and our slope is now 9.


Our equations are:
1) y = 5x - 11
2) y = 9x - 5
