We want to get the difference quotient for the given function, we will get see that the difference quotient is equal to:
f'(x) = 2x + 5
<h3>
The difference quotient:</h3>
For a given function f(x), we define the difference quotient as:

In this case, we have:
f(x) = x^2 + 5x + 6
Replacing that in the difference quotient we get:

Now we can cancel the factor h to get:

So the difference quotient is equal to 2x + 5.

4/16 add all then put your total black over the number you added up
100% ............. 2.20
40% ............. x
-----------------------------
x=40*2.20/100
x=88 / 100
x= 0.88
The answer is x=0.88
<span>the proccess of choosing is independent so probability of choosing from machin1 is:300/1000 =0.3
choosing from machin2 is:707/1010=0.7
the total result is 0.3*0.7=0.21 ;</span>
