Find and simplify the difference quotient of the​ form, <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bf%28x%2Bh%29-f%28x%29%7D%7Bh
Anastasy [175]

With f(x)=-10x+9, we have

f(x+h) = -10(x+h) + 9 = -10x + 9 - 10h

Then the difference quotient is

\dfrac{f(x+h)-f(x)}h = \dfrac{(-10x+9-10h)-(-10x+9)}h = \dfrac{-10h}h = -10

since <em>h</em> ≠ 0.

What two numbers would make:<br> a + b = -11<br> AND<br> a x b = 28
ycow [4]

The first step I would do would be to list the factors of 28.

28(1)

14(2)

7(4)

Now notice that 7 + 4 = 11

So that means that -7 + -4 = -11.

Therefore, -7(-4) = 28

Your two numbers are - 7 and - 4.  Hope that helps!
