If (x + 2 ) is a factor of x3 − 6x2 + kx + 10, k =

Answers

Answer 1

Answer: If a binomial x-a is a factor of a polynomial p(x), then p(a)=0.

x+2 is a factor of p(x)=x³-6x²+kx+10, so p(-2)=0.

$p(-2)=0 \n(-2)^3 - 6 * (-2)^2 + k * (-2) + 10=0 \n-8-6 * 4-2k+10=0 \n-8-24-2k+10=0 \n-2k-22=0 \n-2k=22 \nk=(22)/(-2) \n\boxed{k=-11}$

Answer:

The coordinates of mage of L(5, 10) will be: (11, 3)

So, the 4th (last) option is correct.

Step-by-step explanation:

As we know that Translation means how much a point is moved to the left/right and up/down.

Given the translation maps the point J(1, 4) onto K(7, -3).

As the x-coordinate of the image point K(7, -3) is 7 which is 6 units right to the original point J(1, 4).

Also, the y-coordinate of the image point K(7, -3) is -3 which is 7 units down to the original point J(1, 4)

so it means the translation basically implies that

(x, y) → (x + 6, y - 7)

Hence, the coordinate of the image of L(5, 10) can also be determined by

using the same rule.

(x, y) → (5 + 6, 10 - 7) = (11, 3)

Therefore, the coordinates of mage of L(5, 10) will be: (11, 3)

So, the 4th (last) option is correct.

Simplify fully 4x + 3y -2 + 2x - 8y -6

Answers

Hi, Amyleighx!

First we want to identify any common factors.
4x+3y-2+2x-8y-6
3y-8y=-5y
4x+2x=6x
-2-6=-8
-5y+6x-8

I hope this helps;)

combine like terms. you can combine 4x and 2x, so that is 6x. now combine 3y and-8y and get -5y. combine-2 and -6 and get -8. now put ur terms together. 6x-5y-8
