Step-by-step explanation:
I am confused by what the question is asking
Answer:
Step-by-step explanation:
5 ( y - 2 ) + 3 ( 4 - y )
multiply 5 by both y and -2
5y - 10 + 3 ( 4 - y )
multiply 3 by by both 4 and -y
5y - 10 + 12 - y
hope this helps
Answer:
A
Step-by-step explanation:
To find surface area of a cylinder, find the 2 circles which is the formula a=pi(r)^2, when you get that, multiply that by 2 because both sides count. Than the middle which I would imagine like a soda can. Cut a line right down the middle and hen you take it out, it looks like a Rectangle. Find the circumvented of the circle which would be pi(d)=circumfrence. Now after that you found the top side now the other side is 12 as shown here on the model and multiply thm together you’ll get 84 pi. Now those 2 circles would add up to 32 pi. Add them together youll get 116 pi. Now pi could be any but I’d Use 3.14 which will get you about to A becuase after all 3.14 is an approximate.
Our equation is y = 6x - 5 when simplified. In order to be parallel, the equation for the answer must also have a slope of 6x. This rules out options C and D.
Now just plug in 4 for the x-value for each one to get your answer. A little mental math and I can already tell you it's option A.
6(4) - 14 = y
24 - 14 = y
10 = y
10 = 10
Whereas for option B:
6(4) + 14 = y
24 + 14 = y
38 = y
38 ≠ 10
Option A is your answer.
A₁ = 9
a₂ = 9+2 → a₂ = a₁ + 2. Since it's an AP, d, the common difference is 2
1) Then the recursive formula is :
a(n) = a(n-1) + 2
2) Explicit formula:
It's an AP, with first term a₁, d= common difference and n = number of term, which is the number of rows in this problem.
the value of the nth term is given by the formula is:
value of nth term = a₁ + (n-1).d
3) Number of seats in the 12th row:
9 + (12-1).2 = 31 seats
