Complete the recursive formula of the arithmetic sequence -15, -11, -7, -3,...−15,−11,−7,−3,...minus, 15, comma, minus, 11, comm
o-na [289]
Answer:
c(1) = -15
c(n) = c(n - 1) + 4
Step-by-step explanation:
Given arithmetic sequence is,
-15, -11, -7, -3...........
Common difference between each successive and previous term is,
d = -11 - (-15)
= -11 + 15
= 4
Since recursive formula of the arithmetic sequence is represented by,
a₁ = First term of the sequence
a(n) = a(n - 1) + d
where a(n) is the nth term and a(n-1) is the previous term of the nth term.
Form the given sequence,
c₁ = -15
c(n) = c(n - 1) + 4
Step-by-step explanation:
8x+8−3(x+4)−7(2−x)
8x+8−(3x+12)−7(2−x)
8x+8−(3x+12)−(14−7x)
8x+8−3x−12−14+7x
(8x−3x+7x)+(8−12−14)
12x-18
Answer:
1.) True, because it says three times so you know the x belongs there. Also, you have to follow the order of what the problem says.
2.) False, because it is not in the order of how the problem states it.
3.) False, because if you transfer the fraction to a decimal you get 4.333333. It's not valid.
4.) True, because if you do 7 × 3, it equals to 21. So, 21 - 17 = 4. And Jenny is supposed to have 4 quilts.
Hope it helps! :D
Answer:
There are no solutions
Step-by-step explanation:
a)
20 shirts | 349 + 20(4.8)
40 shirts | 349 + 40(4.8)
60 shirts | 349 + 60(4.8)
(please simplify them yourself)
b) Tn = 349 + n(4.8)
c) (1000 - 349)/4.8 ............... rounded down.
