Answer:
y=14
Step-by-step explanation:
8-4/3-1= 2
so our m=2
now plug it in
4 = 2(1)+b
4 = 2+b
2=b
so it will be
y= 2x+2
y=2(6)+2
y=14
20 divided by 2 = 10 x (5 + 5) = 10 x 10 = 100
Answer:
The value of the land after five years is $23,302.50.
Step-by-step explanation:
First you need to find 3.9% of $19,500 which is $760.5.
Then, you multiply 760.5 by 5 years and you get 3,802.5.
Lastly, you add 3,802.5 to 19,500 and get a total of $23,302.50.

Answer:
y = 2·5^x
Step-by-step explanation:
Using the given points, we can solve for 'a' and 'b'.
y = ab^x
2 = ab^0 = a . . . . . substitute (0, 2) for (x, y)
__
1250 = 2·b^4 . . . . substitute for 'a' and (4, 1250) for (x, y)
625 = b^4 . . . . divide by 2
5 = b . . . . . . . take the 4th root
The function is ...
y = 2·5^x
____
<em>Additional comment</em>
There are two real and two imaginary 4th roots of 625. Only the positive real root is useful as the base in an exponential function like this.
