Answer:
Step-by-step explanation:
85!/82! = 85*84*83 = 592620
n choose 0 is always equals 1
n P n also always equals 1
I believe that is simplified
2.9n+1.7-(1.7)=3.5-(1.7)+2.3n === 2.9n-(2.3n)=1.8+2.3n-(2.3n) === .6n/.6=1.8/.6 === n=3 :)

Answer:
(b) (6, 0)
Step-by-step explanation:
You are given the value of x. Substitute that in the other equation and find the value of y.
-3x +14y = -18
We know x=6 from the second given equation, so ...
-3(6) +14y = -18
Add 18 to both sides
14y = 0
Divide by 14
y = 0
Then the solution is ...
(x, y) = (6, 0)
