Yes, all horizontal lines have the same slope of 0, as it has no change in the y-positions.

Answer: Yes

Step-by-step explanation: For any horizontal or flat line, the slope will always be the same which simplify to 0.

Let's look at an example which I have provided in the first image attached. I have labeled two points on the line and they are point A and point B.

To get from point A to point B along this line, our rise is 0 units and our run is 3 units so our slope or rise over run is 0/3. However, 0/3 can be simplified to 0. So for this line, our slope or <em>m</em> equals 0.

Factor completely.<br><br> x^4-11x^2+28

marissa [1.9K]

Answer:

x⁴ - 11x² + 28

= x⁴ - 4x² - 7x² + 28

= x²(x² - 4) - 7(x² - 4)

= (x² - 7)(x² - 4)

$= (x - \sqrt{7} )(x + \sqrt{7} )(x - 2)(x + 2)$

Algebraic Reasoning please help!

stiv31 [10]

Answer:

$\left[\begin{array}{ccc}7\\4\\2\end{array}\right]$

The answer is a single-column matrix (7,4,2)

Step-by-step explanation:

In such multiplication of matrices, you have to proceed by multiplying each ROW of the first matrix by the COLUMN of the second matrix. So,

$\left[\begin{array}{ccc}3&6&1\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (3 * 2) + (6 * 0) + (1 * 1) = 6 + 0 + 1 = 7$

then...

$\left[\begin{array}{ccc}2&4&0\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (2 * 2) + (4 * 0) + (0 * 1) = 4 + 0 + 0 = 4$

and

$\left[\begin{array}{ccc}0&6&2\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (0 * 2) + (6 * 0) + (2 * 1) = 0 + 0 + 2= 2$

I hope it helps.

-11=(x-3)÷2 what is the solution for x

e-lub [12.9K]

Answer:

-19

Step-by-step explanation:

~ Distribute:

- 11 = 1 / 2 x + -3 / 2

~ Flip the equation:

1 / 2 x + -3 / 2 = -11

~ Use transposition method:

(take -3 / 2 to the other side)

1 / 2 x = -11 - (-3 / 2)

= -19 / 2

x = -12 / 2 * 2

= -19
