Hello,
n=1,2,3,.... and not 0
Answer B a(n)=-2*n
Answer:
They have the same value when x=5
Step-by-step explanation:
4x
Let x = 4
4*5 = 20
15+x
Let x =5
15+5 = 20
They have the same value when x=5
a(n) = 6n - 7
a(12) = 6(12) - 7
a(12) = 72 - 7
a(12) = 65
The answer is B.
20 + 25(times the number of hours) = 282.50
You add the 20 because of the one time service fee.
Now lets work this out.
20 + 25x =282.50
25x = 262.50 (subtract both sides by 2 to get the x's alone)
x = 10.5 (divide both sides by 25 to get just x)
x = 10.5 hours
So the answer is A.
