Determine if the expression -8c-9c^4d^2−8c−9c

Leto [7]

Answer:

$-8c-9c^4d^2-8c-9c$ is a polynomial of type binomial and has a degree 6.

Step-by-step explanation:

Given the polynomial expression

$-8c-9c^4d^2-8c-9c$

Group like terms

$=-9c^4d^2-8c-8c-9c$

Add similar elements: -8c-8c-9c=-25c

$=-9c^4d^2-25c$

Thus, the polynomial is in two variables and contains two, unlike terms. Therefore, it is a 'binomial' with two, unlike terms.

Each term has a degree equal to the sum of the exponents on the variables.

The degree of the polynomial is the greatest of those.

25c has a degree 1

$-9c^4d^2$ has a degree 6. (adding the exponents of two variables 'c' and 'd').

Thus,

$-8c-9c^4d^2-8c-9c$ is a polynomial of type binomial and has a degree 6.

Hey there! I'm happy to help!

Lines that are parallel have the same slopes because they are increasing or decreasing at the same rate and therefore will never bump into each other.

We see that y=2 has a slope of 0 because there is no x that we can see in the equation. This is just a flat line.

If the line we are looking for is flat; it stays at the same y-value the entire time. We see that the y-value for this line of ours is -6. Therefore, the answer is C. y=-6.

I hope that this helps! Have a wonderful day!
