Find the slope of the line.

galben [10]

Answer:

0.5

Step-by-step explanation:

From the figure the line passes through the points (0,2) and (4,4).

The slope of the line that passes through the points $(x_1,y_1)$ and $(x_2,y_2)$ is always

$m=\dfrac{y_2-y_1}{x_2-x_1}.$

Therefore, the slope of the graphed line is

$m=\dfrac{4-2}{4-0}=\dfrac{2}{4}=\dfrac{1}{2}=0.5.$

There are 5 red marbles, 4 blue marbles and 7 black marbles in a bag. Like the theoretical P(choosing a red)

Kryger [21]

Answer:

$\frac{5}{16}$

Step-by-step explanation:

1. To find the answer, add up all the marbles.

4+5+7= 16

2. Because 16 is the total number of outcomes, it will be the denominator.

$\frac{}{16}$

3. Because 5 is the number of desireable outcomes, it will be the numerator.

$\frac{5}{16}$

(Note: the decimal equivalence is 0.3125).

(Note: the ratio equivalence is 5:16).

(Note: the percent equivalence is 31.25%).

Factor completely. -2k - k3^ - 3k^2

wlad13 [49]

Answer:

$-k(k+1)(k+2)$

Step-by-step explanation:

Begin to factor by using GCF by finding the greatest common factor. Here it is k.

$-2k-k^3-3k^2 = -k(2+k^2+3k)$

We will rearrange and factor the trinomial.

$-k(2+k^2+3k)\\-k(k^2+3k+2)\\-k(k+1)(k+2)$
