Answer:
1. 5 – x = 8 , x = -3
2. -1 = x – 2 , x = 1
3. -3x = 9 , x = -3
4. -10 = -5x , x= 2
Step-by-step explanation:
For this case we have a function of the form:

Where,
A: it is the initial amount
b: is the growth rate
x: is the number of years
Substituting values we have:

We have a growing exponential function because the value of b is greater than 1.

Answer:
option 2 I think sorry if its incorrect
0.68 = 0.6 + .08 = 6 x 0.1 + 8 x .01
They should all equal 0.68 :)
By using and X,Y grid starting at zero and then making its way to 1,4 for example showing that for every 1 X there are 4 Y's
