Answer:

<u>Actually there are two answers: -3 and 0, depending on how the expression is written.</u>

Step-by-step explanation:

If the rational expression is x - 4/x - 6, we have:

x - 4/x - 6

= 4 - 4/4 - 6

= 4 - 1 - 6 = 4 - 7 = -3

If the rational expression is (x - 4)/(x - 6), we have:

(x - 4)/(x - 6)

= (4 - 4)/(4 - 6)

= 0/-2 = 0

Find the value of x if a linear function goes through the following points and has the following slope: (x,2), (-4,6), m=3
Anastasy [175]

The slope is defined as

m=\dfrac{\Delta y}{\Delta x}=\dfrac{6-2}{-4-x}

So, we have the follwing equation:

\dfrac{6-2}{-4-x} = 3 \iff 4 = 3(-4-x) \\\iff 4=-12-3x \iff16=-3x \iff x = -\dfrac{16}{3}
