Which of the following is an example of an open equation?
An open equation is an equation with at least one variable.
Therefore, 5x + 7 = 12 is an open equation.

Which of the following equations has 3 as a solution
z ‒ 15 = ‒12
z = -12 + 15 = 3

Is (1, 5) a solution to the equation y = x – 2?
5 ≠ 1 - 2
-5 ≠ -1
no

Is (–2, –6) a solution to the equation y = 3x?
-6 = 3(-2)
yes

Which of (3, 5), (4, 6), (5, 7), and (6, 8) are solutions to y = x + 2
5 = 3 + 2
6 = 4 + 2
7 = 5 + 2
8 = 6 + 2
all

Which equation would be used to generate the data in the following table?
x y
1 8
2 16
3 24
4 32
y = 8x

Identify each function that has a remainder of -3 when divided x+6
Sergeu [11.5K]

Answer:

D

Step-by-step explanation:

According to remainder theorem, you can know the remainder of these polynomials if you plug in x = -6 into them.

<em>So we will plug in -6 into x of all the polynomials ( A through D) and see which one equals -3.</em>

<em />

<em>For A:</em>

x^5 + 2x^2 - 30x + 30\\=(-6)^5 + 2(-6)^2 - 30(-6) + 30\\=-7494

For B:

x^4 + 4x^3 - 21x^2 - 53x + 12\\=(-6)^4 + 4(-6)^3 - 21(-6)^2 - 53(-6) + 12\\=6

For C:

x^3 - 10x^2 - 7\\=(-6)^3 - 10(-6)^2 - 7\\=-583

For D:

x^4 + 6x^3 - 10x - 63\\=(-6)^4 + 6(-6)^3 - 10(-6) - 63\\=-3

The only function that has a remainder of -3 when divided by x + 6 is the fourth one, answer choice D.
