Step-by-step explanation:
Answer:
B) 7(7 + 3)
Step-by-step explanation:
7(7 + 3) = 49 + 21
Replace P with 15:
d = -3(15)^2 + 168(15) - 315
d = -3(225) + 2520 - 315
d = -675 + 2520 -315
d = 1530
Answer:
![- 1.6](https://tex.z-dn.net/?f=%20-%201.6)
Step-by-step explanation:
To find the slope, use the equation
![\frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20)
where (-1, 7) and (4, -1) is (x1, y1) and (x2, y2) respectively.
Hence, the slope will be
![\frac{ - 1 - 7}{4 - ( - 1)}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%201%20-%207%7D%7B4%20-%20%28%20-%201%29%7D%20)
Simplify:
![\frac{ - 8}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%208%7D%7B5%7D%20)
or
![- 1.6](https://tex.z-dn.net/?f=%20-%201.6)
