You can go through the effort of determining the zero of the function analytically and evaluating an analytic expression for the derivative at that point, or you can let a graphing calculator do that heavy lifting. Since the numbers have to be "nice" for your equation to have the desired form, it is easy to know what to round to in the event that is necessary (it isn't).
We find the positive zero-crossing at x=2, and the slope of the curve at that point to be 8. Thus the line will have slope -1/8 and can be written as
.. x +8y -2 = 0
D>7
To write an inequality means to write an expression where one side is greater than the other, or less than the other. In this case, we are to write an inequality that shows that John will have more than 7 dollars in his bank account. The variable we are to use is d, which will represent the number dollars in his bank account. If he wants to have more than seven dollars, then d will have to be greater than seven.
Both are the same because the first line is going by ×2 so the missing number would be 22. The second line is going by +1 so 21+1=22. (Hope this will prove your friend wrong :3)
