The answer is <span> B- y=4-1.5x
</span><span>David is rowing a boat upstream, so the river is slowing him down. Thus, the net speed is 6 mph - 2 mph = 4 mph.
Since David's speed </span><span>decreases at a rate of 1.5 miles per hour, after x hours his speed y will be:
y = 4 - 1.5 x</span>

The domain for n is 
Explanation:
The arithmetic sequence is
To determine the domain of the sequence, let us consider
as
Thus, the sequence becomes,
The domain of the function is the set of all x-values for which the function is real and well defined.
Since, the function has no domain constraints or undefined points. Therefore, the domain of the function is
Thus, the domain of the arithmetic sequence
is 
Answer:
x=5
Step-by-step explanation:
So first you would subtract 2x from both sides to get:
1x = 5
Then you divide both sides by 1:
x = 5
Answer:
13366.25 in³
Step-by-step explanation:
The volume of a box can be found by multiplying the base area and height together.
Volume of a box
= base area ×height
= 314.5(8.5)
= 2673.25 in³
Volume of 5 boxes
= 5(2673.25)
= 13366.25 in³
