Use the remainder theorem and the factor theorem to determine whether (b + 4) is a factor of (b3 + 3b2 − b + 12).

8 0

Use synthetic division. Look at my attachment below for a detailed explanation. If the remainder is 0 (which it is), then it's a factor.

Find the slope (8,-5) (8,10)

andreev551 [17]

Finding the slope using two points:

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

$y_{2} =10\\y_{1} =-5\\x_{2} =8\\x_{1} =8$

^^^Plug these numbers into the formula for slope...

$\frac{10-(-5)}{8-8$

$\frac{15}{0}$

Your slope is undefined. This means that you line is vertical

Hope this helped!

What two numbers multiply to negative 8 but add to negative 7

Amiraneli [1.4K]

Let "a" and "b" be the two numbers
So a*b=-8 and a+b=-7
Therefore S=-7 and P=-8
Using (x^2)-S+P=0 => (x^2)-(-7)+(-8)=0 => (x^2)+7-8=0
By factorizing we get (x+8)(x-1)=0
So a can be either -8 or 1 and b can be 1 or -8
Meaning that the two numbers are -8 and 1.
