ALGEBRA 1
1 answer:
The main thing about a polynomial is it's the sum of terms, each a constant coefficient times whole number power (0, 1, 2, 3, ...) of the variable.
A. 35x² is a polynomial; the power 2 is a whole number. There's only one term so not really the sum of terms, but one's enough.
B.
That's a perfectly good polynomial but you might not have gotten to it in algebra I yet. The square root of negative 1 is abbreviated <em>i</em> and when we add it to the set of real numbers we get complex numbers. It has a complex coefficient 4+i but that's OK in a polynomial.
If you haven't gotten to complex numbers yet you might be expected to answer no to this one. I don't know.
C.
The negative exponent means this isn't a polynomial.
D. x/5 + 2
That's fine, just another way of writing
which is a perfectly ok polynomial.

I assume you mean
there is a common factor of 9 in the numerator and denominator so we can cancel out to form

Given:
The table of values.
To find:
The equation that best represents the relationship.
Solution:
From the given table it is clear that the value of x increasing by 2 and the value of y increasing by 3. Since y is increasing at a constant rate with respect to x, therefore the given table represents a linear relationship.
Consider any two points from the given table. Let the two points are (2,2) and (4,5). So, the equation of the line is
On further simplification, we get
Therefore, the correct option is A.
