Answer:
The other factor is (x + 2).
Step-by-step explanation:
If x - 10 is a factor of x^2 - 8x - 20 then we must find another factor that includes +2x, so that we have -10x + 2x = -8x. That factor is (x + 2):
x^2 - 8x - 20 = (x - 10)(x + 2)
As a test, multiply -10 and +2. We get -20, matching the constant of the given polynomial. Also, -10x + 2x = -8x, another match.
The answer is x=3 and y= -2/3
You can either add the equation to find x first or subtract to find y first
Either way it will work

Step-by-step explanation:
The graph is an arrow pointing left with an open circle at x=-12.
Answer:
![I = \pm \sqrt{\dfrac{P}{R}}](https://tex.z-dn.net/?f=%20I%20%3D%20%5Cpm%20%5Csqrt%7B%5Cdfrac%7BP%7D%7BR%7D%7D%20)
Step-by-step explanation:
![P = I^2R](https://tex.z-dn.net/?f=%20P%20%3D%20I%5E2R%20)
Divide both sides by R.
![\dfrac{P}{R} = I^2](https://tex.z-dn.net/?f=%20%5Cdfrac%7BP%7D%7BR%7D%20%3D%20I%5E2%20)
Switch sides.
![I^2 = \dfrac{P}{R}](https://tex.z-dn.net/?f=%20I%5E2%20%3D%20%5Cdfrac%7BP%7D%7BR%7D%20)
Take the square root of both sides.
![I = \pm \sqrt{\dfrac{P}{R}}](https://tex.z-dn.net/?f=%20I%20%3D%20%5Cpm%20%5Csqrt%7B%5Cdfrac%7BP%7D%7BR%7D%7D%20)
