Step-by-step explanation:
multiply gallon by price of gas
C. velocity includes the direction of travel whereas speed does not.
Given

We have to set the restraint

because a square root is non-negative, and thus it can't equal a negative number. With this in mind, we can square both sides:

The solutions to this equation are 7 and -2. Recalling that we can only accept solutions greater than or equal to -1, 7 is a feasible solution, while -2 is extraneous.
Similarly, we have

So, we have to impose

Squaring both sides, we have

The solutions to this equation are 5 and 10. Since we only accept solutions greater than or equal to 7, 10 is a feasible solution, while 5 is extraneous.

Answer:
I think that the answer is A) $0.50
Step-by-step explanation:
So, if you want to figure out how much the strawberries cost for year 0, all you have to do is go to the point (0,4). For the first year the price of the strawberries have increased to 4.50. I know this because when you look at the graph, it looks like the point is in the middle of 4, which makes 4.50. So the price of the strawberries in year 1 is (1, 4.50). The price for year two is (2, 5) and so forth. This is what the pattern would be (0,4) (1, 4.50) (2, 5) (3, 5.50) (4,6) (5, 6.50) (6, 7) (7, 7.50) (8,8) (9, 8.50) (10, 9).......etc.
