Find the derivative of f(x)=4x+7 at x=5

The derivative f'(x) of a function f(x) gives us a way of finding the <em>instantaneous rate of change </em>of that function for any value of x.

Here, we're given the function f(x) = 4x + 7. This function describes a <em>line</em>, and the defining quality of a line is the fact that it has a <em>constant rate of change</em>. This rate of change is described by the slope of the line, which in this case is 4, so we'd say that the rate of change - the derivative - of f(x) for every value of x is 4.

It'll be 4 at x = 1, it'll be 4 at x = 5,and it'll still be 4 at x = 1,000,000

I need to increase my sales by 35% this month I’m currently at 45 sales how many sales do I need to meet my goal ?
telo118 [61]
Assume that 100% = 45 sales and 35% = X sales amount

You can create a ratio to help you solve for x

45 = 100%
x   =  35 %

Which is equal to this fraction:  (45/x) = (100/35)

Solving for X by cross multiplying and dividing by 100:
  [(45)(35)] / 100  =  X = 15.75 = 16 sales (rounded up)

You would need at least 16 sales to increase sales total by 35%
