Answer:
<h3>D</h3>
Step-by-step explanation:
Answer:
(x² - 3)(x² + 3)(
+ 9)
Step-by-step explanation:
- 81 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
- 81
= (
)² - 9²
= (
- 9)(
+ 9) ←
- 9 is also a difference of squares
= (x² - 3)(x² + 3)(
+ 9)
The answer to this question is D (2,-2)
Answer:
r = -17
Step-by-step explanation:
Slope = -5
Slope = ![\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
![\frac{3 - r}{-8-[-4]}=-5\\\\\frac{3-r}{-8+4}=-5\\\\\frac{3-r}{-4}=-5\\](https://tex.z-dn.net/?f=%5Cfrac%7B3%20-%20r%7D%7B-8-%5B-4%5D%7D%3D-5%5C%5C%5C%5C%5Cfrac%7B3-r%7D%7B-8%2B4%7D%3D-5%5C%5C%5C%5C%5Cfrac%7B3-r%7D%7B-4%7D%3D-5%5C%5C)
3-r = (-5)*(-4)
3 - r = 20
-r = 20 - 3
-r = 17
r = -17
