~Subtract 10 to both sides
k = 17
Best of Luck!
Answer:
a) 1 (the slope)
b) for every one ounce of sugar you eat, you can one ounce of weight
Answer:
A. 
Step-by-step explanation:
The options are:

For this exercise it is important to remember that, by definition, the Exponential parent functions have the form shown below:

Where "a" is the base.
There are several transformations for a function f(x), some of those transformations are shown below:
1. If
and
, then the function is stretched vertically by a factor of "b".
2. If
and
, then the function is compressed vertically by a factor of "b"
Therefore, based on the information given above, you can identify that the function that represents a vertical stretch of an Exponential function, is the one given in the Option A. This is:

Where the factor is:

And 
he is wrong because 0.1 is also 0.10 greater than 0.09
