A dolphin travels at an average of 10 mi/h in still water. The dolphin travels 75 miles downstream with the east coast current and 75 miles upstream against
the east coast current in a total of 18 hours. What is the average speed of the
current in this section of the Atlantic Ocean? Round to the nearest tenth.

answer: b.

step-by-step explanation:

it is b. cause the equations are put in the right category

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
