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.

Kryger [21]

Answer:

\frac{5}{16}

Step-by-step explanation:

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

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 <u>decimal equivalence</u> is 0.3125).

(Note: the <u>ratio equivalence</u> is 5:16).

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)
