A characteristics of an exponential decay function is it has a constant term that is lesser than 1, this is because when you raise it a number that is lesser than 1 to higher values the result will be lesser and lesser, that is why it is called decay function. so the decay functions are a. f(x)=0.9^x and d. <span>j(x)=(4/5)^x</span>
Answer:

Step-by-step explanation:
You don't know the number, so you replace it with x.
Since it is one third of x, you multiply x by 
Then you subtract 5 from the whole thing: 
So a line is 180 degrees. These angles would equal 180. So 180= w + (3w -28). You add 28 too 180, getting 208. Then divide by the 4w. Leading you to w= 52. Plug into the equations to make sure everything checks out
Answer:
Step-by-step explanation:
4*(-2)-3
-8-3
-11
Answer:
x - a smaller number
(x+1) - a larger number
3(x+1) - 2x = 34
3x + 3 - 2x = 34
x= 31
(x+1) = 32
