Which description is correct for the polynomial 5x³?
2 answers:
Answer: The answer is (D) cubic monomial.
Step-by-step explanation: The given polynomial is
We are to select the correct description of the above polynomial from the given options.
Since there is only one term in the polynomial, so it is a monomial.
Also, the power of the unknown variable is 3, so the degree of the polynomial is 3 and so it is a cubic polynomial.
Therefore, the given polynomial is a cubic monomial.
Thus, (D) is the correct option.

Answer:
The given point is a solution to the given system of inequalities.
Step-by-step explanation:
Again, we can substitute the coordinates of the given point into the system of inequalities. We know that the x-coordinate and y-coordinate of are
and
, respectively.
Plugging these values into the first inequality, , gives us
, which simplifies to
. This is a true statement, so the given point satisfies the first inequality. We still need to check if it satisfies the second inequality though, because if it doesn't, it won't be a solution to the system.
Plugging the coordinates into the second inequality, , gives us
, which simplifies to
. This is also a true statement, so the given point satisfies the second inequality as well. Therefore,
is a solution to the given system of inequalities since it satisfies all of the inequalities in the system. Hope this helps!
