Answer:
The given situation is in direct variation.
The dependent variable is the distance covered and the independent variable is the number of hours.
Step-by-step explanation:
We are given the following information in the question:
Steve drove 300 miles in 5 hours.
After stopping for gas, he drove an additional 120 miles in 2 hours.
We calculate the ratios and if these ratios are equal then, we can say that the situation represent a direct variation.
For direct variation, the equation is of the form y = kx that is , we can write,
To check the ratio:
Thus, the given situation is in direct variation.
The dependent variable is the distance covered and the independent variable is the number of hours.
Answer: The answer is a polynomial in two variables with degree 3.
Step-by-step explanation: We are given to write the properties of the polynomial
We can see that the polynomial 'p' contains two unknown variables 'x' and 'y'.
Also, the degree of the polynomial is the degree of the expression
Therefore, the degree of the polynomial will be 2 + 1 = 3.
Thus,
(i) the polynomial has two unknown variables 'x' and 'y', and
(ii) Its degree is 3.
