Step-by-Step Solution

Verified
Answer

The polynomial has degree 1 and leading coefficient -1.

1Step 1. Write down the given information.

The given polynomial is 7-x.

2Step 2. Calculation.

Re-arranging the given polynomial in descending order of degree, the polynomial can be written as -x+7.

Now, the degree and leading coefficient of the given polynomial -x+7 are stated as:

The given polynomial is a polynomial in one variable x. Therefore, by concept of degree and leading coefficient of a polynomial, the degree of the polynomial is 1 and leading coefficient is -1.

3Step 3. Conclusion.

The polynomial has degree 5 and leading coefficient -3.
