y-9x=3
9x-y=2
27x-3y=2
The requried line is not parallel to the graph of y = 9x + 1 is 1. 9y - x = 2. Option A is correct.
To determine which line is not parallel to the graph of y = 9x + 1, we need to compare the slopes of each line to the slope of y = 9x + 1.
The equation y = mx + b represents a line with slope m. In the case of y = 9x + 1, the slope (m) is 9.
Now, let's check the slopes of each equation given:
A. 9y - x = 2:
To write this equation in the form y = mx + b, we rearrange it as y = (1/9)x + 2/9. The slope is (1/9), which is not equal to 9. Therefore, this line is not parallel to y = 9x + 1.
B. y - 9x = 3:
Rearranging this equation as y = 9x + 3, we can see that the slope is 9, which is equal to the slope of y = 9x + 1. Therefore, this line is parallel to y = 9x + 1.
C. 9x - y = 2:
Rewriting this equation in the form y = mx + b, we get y = 9x - 2. The slope is 9, which is equal to the slope of y = 9x + 1. Therefore, this line is parallel to y = 9x + 1.
D. 27x - 3y = 2:
To put this equation in the form y = mx + b, we divide both sides by 3, which gives 9x - y = 2/3. The slope is 9, which is equal to the slope of y = 9x + 1. Therefore, this line is also parallel to y = 9x + 1.
In summary, the line not parallel to the graph of y = 9x + 1 is 1. 9y - x = 2. Option A is correct.

The price of the notebook experienced a percentage increase of 7.9%.
The subject of this problem is in the area of mathematics, specifically on percentage increase. To find the percentage increase in the price of the notebook, you first find the difference in price. The difference is $3.40 - $3.15 = $0.25. Next, you divide the increase by the original price, which gives you: $0.25 / $3.15 = 0.079365. Then, to turn this into a percentage, multiply the result by 100 to get 7.9365%. Rounding this to the nearest tenth, we get 7.9%.

The domain contains only natural numbers
.
Exponential bases must be whole numbers.
Initial values must be whole numbers.
The correct answer is:
The domain contains only natural numbers .
Explanation:
The domain of a geometric sequence is the set of term numbers. This is the position of each term in the sequence: first, second, third, etc.
Since the domain is the set of positions, there are no decimal or fraction numbers in the domain. There would be no "2 and a half" term; it goes from the second to third.
This means that the values between the terms of the sequence have no value, and the graph will not be connected.
Answer: B.
(The domain contains only natural numbers.)
Step-by-step explanation:
B.) x = -2
C.) x = -1
D.) x = 3
Answer:
The right answer is x= -2
