Answer:
2
Step-by-step explanation:
because they're consecutive, each integer has to come right after the one before it.
if 1st integer is 1, the 2nd should be 2, and the 3rd should be 3.
3 is equal to 1 + 2, or n + 2
hopefully that works
x+y = -19
x*y = 35
x=-19-y
(-19-y)y = 35
y^2 +19y +35 = 0
y = -2.066965626
therefore x=35/y = -16.93303437
Answer:
224
Step-by-step explanation:
We will need the following rules for derivative:
Sum rule.
Constant multiple rule.
Power rule.
Slope of y=x is 1.


by sum rule.
by constant multiple rule.
by power rule.

Now we need to find the derivative function evaluated at x=9.



In case you wanted to use the formal definition of derivative:

Or the formal definition evaluated at x=a:

Let's use that a=9.

We need to find f(9+h) and f(9):


(used foil or the formula (x+a)(x+a)=x^2+2ax+a^2)

Combine like terms:





Ok now back to our definition:


Simplify by doing 1044-1044:

Each term has a factor of h so divide top and bottom by h:
