ALGEBRA 1
lukranit [14]

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. 4x + x \sqrt{-1} = (4+i)x

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.  7x^7 - x^{-5}

The negative exponent means this isn't a polynomial.

D. x/5 + 2

That's fine, just another way of writing

\frac 1 5 x + 2

which is a perfectly ok polynomial.

Answer: A B D

15 POINTS easy and will give BRAINLY a THANKS and 5 STARS
4vir4ik [10]

Use DESMOS and then take the points that are given and then plug them into your equations to show your work.

Desmos helps all equation problems that you need solved because it not only solves it, but also has it graphed with marked points.

It helped me through highschool.

HELP ME ASAP PLEASE a) A graph is drawn below.
Vesna [10]
Directly proportional means if x has a certain value, y should have the same value. but here in the graph, when x is 0, y has a value greater than 0. for x and y to be directly proportional, the line should go through 0.
