<span>since h=2t+3
i.e. at h=13 we find
13= 2t+3
i.e. 13-3= 2t
10=2t
i.e. t=10/2
i.e. t=5 days
similarly at h=27
we find
27= 2t+3
i.e. 27-3= 2t
24=2t
i.e.
t=24/2
i.e.
t=12 days
hence in 5 and 12 days the height of the tomato plant will be between 13 and 27 inches respectively.</span>
Answer:
A) 7x + 3y = -8
B) -4x - y = 6 Multiplying B) by 3
B) -12x -3y = 18 then we add A)
A) 7x + 3y = -8
-5x = 10
x = 2
y = -2
Answer is the first one (2, -2)

Step-by-step explanation:
Answer:
I think the common difference is 2. The formula to create the sequence is n (number) is multiplied by 2.
1 x 2 = 2
2 x 2 = 4
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
64 x 2 = 128
128 x 2 = 256
256 is the 8th term of the sequence. Since your question says that we should look for the sum, add the number of the sequence I guess.
2 + 4 +8 + 16 + 32 + 64 + 128 + 256 = 510
