Three times a number = 3x
Increased by 8 = + 8
So far we have: 3x + 8
no more than = <=
the number decreased by 4 = x -4
Put it all together and we have:
3x + 8 <= x - 4
Solve for x
3x + 8 <= x - 4
3x - x <= -4 - 8
2x <= -12
2x / 2 <= -12 / 2
x <= -6
-6 is the number / answer.
Answer:
.
Step-by-step explanation:
We have been given that 
and 
. We are asked to write N as a discrete exponential function of t of the form 
.
Using our given information, we can set an equation as:
Using our given information, we will get:
Substitute the given values:
Switch sides:
Take 11th root of both sides:
![\sqrt[11]{(1+r)^{11}}=\sqrt[11]{1.5476190476190476}](https://tex.z-dn.net/?f=%5Csqrt%5B11%5D%7B%281%2Br%29%5E%7B11%7D%7D%3D%5Csqrt%5B11%5D%7B1.5476190476190476%7D)
Therefore, our required function would be .
