Which statement is true about the polynomial
–3x4y3 + 8xy5 – 3 + 18x3y4 – 3xy5 after it has been fully simplified?
it has 3 terms and a degree of 5.
it has 3 terms and a degree of 7.
it has 4 terms and a degree of 5.
it has 4 terms and a degree of 7.

C. It has 4 terms and a degree of 5.

Step-by-step explanation:

We have been given a polynomial .

First of all, we will combine like terms of our given polynomial as:

Now, we will arrange our given polynomial with greatest degree in leading term as:

We can see the greatest degree for our given polynomial is 5 and the number of terms of our given polynomial is 4, therefore, option C is the correct choice.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
