What is the value of n? 121 144

N76 [4]

Answer:

C. $y - 8 = -0.2 (x+10)$

Step-by-step explanation:

Slope

So first we need to find the slope in order to answer the question. To find the slope, we need to choose any two points from the table.

The slope equation is $m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ .

Let's use point (10,4) and point (15,3).

Now let's substitute those values into the slope equation. That gets to $m = \frac{3-4}{15-10}$ .

Now let's simplify that to $m = \frac{-1}{5} = -\frac{1}{5}$ . Therefore, the slope is $-\frac{1}{5}$ . In other words, it is also $-0.2$ .

Point-Slope Form

Now we need to plug in the numbers into the point slope form.

The point-slope form is $y - y_{1} = m(x-x_{1})$ .

Let's plug in the slope (m) into the equation. That gets to $y - y_{1} = -0.2 (x-x_{1})$ .

Now let's use (-10,8) in the equation since that's what it states in the problem. Doing that would lead to $y - 8 = -0.2 (x--10)$ . In other words, that is $y - 8 = -0.2 (x+10)$ .

Therefore, the answer has to be c. $y - 8 = -0.2 (x+10)$ .

Hope this helped! If not, please let me know! <3

CORRECT ANSWER WILL BE MARKED BRAINLIEST!!

Kisachek [45]

To create the new figure, we must multiply each coordinate by the scale factor, which is 1/2 in this case.

So j(-2,2) becomes j'(-1,1)

K(4,2) becomes K'(2,1)

L(4,-2) becomes L'(2,-1)

and M (-2,-2) becomes M'(-1,-1)

The scale factor is between 1 and 0 which means that this dilation is a reduction that will shrink the original figure to a smaller one.

The volume of a box (v) varies directly with its length (l) if one of the boxes has a volume of 325 cubic inches and a length of

stiks02 [169]

Answer:

The constant of proportionality for the group of boxes is: 25

Step-by-step explanation:

Proportion means that change in one quantity causes change in other quantity. Direct variation means that increase in one quantity causes increase in the other quantity.

Let l be the length and v be the volume

Then according to given statement

V∝l

Removing the proportionality symbol introduces a constant in the equation

$V = kl$

Putting V = 325 and l = 13

$325 =k(13)\\k = \frac{325}{13}\\k = 25$

Hence,

The constant of proportionality for the group of boxes is: 25
