Identify each function that has a remainder of -3 when divided x+6

Sergeu [11.5K]

Answer:

Step-by-step explanation:

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

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

For A:

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

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.

There are 48 cards in a pack and each card is either red or black.

Anon25 [30]

Answer:

Step-by-step explanation:

Red:black = 1:1

Red cards = x

Black cards =x

x + x = 48

2x = 48

x = 48/2

x = 24

No. of red cards = 24

No of black cards = 24

Now 8 red cards are removed

So, No. of red cards = 24 - 8 =16

Red: Black = 16:24

$=\frac{16}{24}=\frac{2}{3}$

Red: Black = 2:3

Lines m and p are perpendicular. If the slope of line m is -3, what is the slope of line p?

nika2105 [10]

Answer: The slope of p is 1/3

Step-by-step explanation:

If the lines are perpendicular, this means they are opposite.

Thus, O is opposite P and since O = -3, P = 1/3
