Amber is starting a garden. She plants 2 flowers the first month. The next month, she plans three times more flowers (6 flowers)
Artist 52 [7]
This is a geometric progression problem. We can the general formula that can tell us how many flowers would be planted each month.
Let's write the terms that we know and see if we can find the pattern:
&#10;\begin{tabular}{lll}&#10;Month & Number of flowers planted & Different form            \\&#10;1     & 2                         & 2\cdot3^0 \\&#10;2     & 6                         & 2\cdot3^1 \\&#10;3     & 18                        & 2\cdot3^2 \\&#10;4     & 54                        & 2\cdot3^3&#10;\end{tabular}&#10;\end{table}
The patern here is obvious. Let's write it down:
N=2\cdot3^{n-1}
This formula gives us a number of flowers planted in the n-th month.

Ivory says that the equation 2x+2=x+1 has no solution because the left-hand side is double the right-hand side. Is Ivory Correct
lorasvet [3.4K]

Answer:

No, Ivory is incorrect. The equation does have a solution, and the solution is x = -1.

Step-by-step explanation:

We try to solve the equation first.

2x + 2 = x + 1

We want all variables on the left side and all numbers on the right side.

Subtract x from both sides.

x + 2 = 1

Subtract 2 from both sides.

x = -1

Check: Plug in -1 for x on both sides and see if it makes a true statement.

2x + 2 = x + 1

2(-1) + 2 = -1 + 1

-2 + 2 = 0

0 = 0

0 = 0 is a true statement, so the solution x = -1 is the correct solution.

Answer: Ivory is incorrect. The equation does have a solution, and the solution is x = -1.
