Answer:
Statements (1) and (2) TOGETHER are NOT sufficient.
Step-by-step explanation:
If y ≠ 1, is x = 1 ?
(1)
= 1
(2) y = 1 – x
The two statements are not sufficient to assert this claim. The statement If y ≠ 1, is x = 1 only holds in the two statements if y=0 as seen below.
(1)
= 1

x=1
(2) y = 1 – x
0=1-x
x=1
Every other value of y fails the condition. So a sufficient statement would have been:
If y ≠ 1, and y=0, is x = 1 ?
(1)
= 1
(2) y = 1 – x
The answer is 24. I believe.
Let's begin by defining the key terminologies:
The degree of a polynomial simply refers to the term with the highest exponent in a polynomial
For example:

The leading coefficient simply refers to the coefficient of the term that has the highest degree in a polynomial
For example:
Thirteen feet and eight inches
