12x - 18 - 4x -2
12x - 4x = 8x (yours 12x - 4x = 8)
-18 - 2 = -20 (yours -18 -1 = 17)
answer:
8x - 20
Answer:
11,880 different ways.
Step-by-step explanation:
We have been given that from a pool of 12 candidates, the offices of president, vice-president, secretary, and treasurer will be filled. We are asked to find the number of ways in which the offices can be filled.
We will use permutations for solve our given problem.
, where,
n = Number of total items,
r = Items being chosen at a time.
For our given scenario
and
.





Therefore, offices can be filled in 11,880 different ways.
Answer:
X+0.375=y
Step-by-step explanation:
Answer:
y = -2x + 6
Step-by-step explanation:
Point slope form is y - y1 = m(x-x1)
y - (-2) = -2(x-4)
y + 2 = -2x + 8
y = -2x + 6
(4 sec) * (-10 ft/sec) = -40 ft.
