Answer:
The answer for the question is D. 1/x^8
Let's check every choices until one choices satisfy the graph :
Choice A is just a translation of -5 units or 5 units to the left
If we look at the graph between A"B"C" and A'B'C'
A"B"C" is 5 units to the left of A'B'C'
Therefore Choice A is True!
The correct answer is A.
No need to check for the other choices since you got a true statement at the first Choice.
IF in case that A is False, then you need to check the other choices.
1. 4/9
2.4
3. 9
4. 1/2
5. 2/-9
6. -1
7. 1
8. 7/4
When finding slope you want to subtract Y1 - Y2 and X1 -X2 to get your answer
Answer: the number of boats that are in the marina is 105.
Step-by-step explanation:
Let x represent the number of boats that are in the marina.
Two-thirds of the boats in the marina are white. It means that the number of white boats in the marina is
2/3 × x = 2x/3
The remaining number of boats will be
x - 2x/3 = x/3
4/7 of the remaining boats are blue. It means that the number of boats that are blue is
4/7 × x/3 = 4x/21
The number of boats left would be
x/3 - 4x/21 = 3x/21
If there are 15 red boats, it means that
3x/21 = 15
3x = 21 × 15 = 315
x = 315/3
x = 105
