Answer:
D
Step-by-step explanation:
using the definition of n
= ![\frac{n!}{(n-r)!}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D)
where n! = n(n- 1)(n - 2)......× 3 × 2 × 1
here n = 7 and r = 4, hence
7![P_{4}](https://tex.z-dn.net/?f=P_%7B4%7D)
= ![\frac{7!}{3!}](https://tex.z-dn.net/?f=%5Cfrac%7B7%21%7D%7B3%21%7D)
=
← cancel 3 × 2 × 1 leaving
7
= 7 × 6 × 5 × 4 = 840 → D
The answer is 8 + 4x
As you multiply the 4 by the 2 to get 8, then multiply the 4 by the x. Hope that helped

The correct answer is C) y + 5 = 2(x + 3)
In order to find this, simply take the point and the slope and plug into the base form of point-slope form.
y - y1 = m(x - x1)
Use the slope for m and the point for (x1, y1)
y + 5 = 2(x + 3)
