it would be B

you can put any number in for k, but if it is greater than a 2, it’ll make the statement false

Answer:

[tex]y=-\frac{2}{5} -1[/tex]

Step-by-step explanation:

So first thing is that slope intercept form is setup like this

y=mx+b

m=slope

b=y intercept

the slope is change in y over change in x

as y goes down 2 x goes up 5

so the slope is -2/5

the y intercept is at (0,-1) so the y intercept is -1

therefore the answer is

[tex]y=-\frac{2}{5} -1[/tex]

have a great day :)

Answer:

[tex]y=-\frac{2}{5}x-1[/tex]

Step-by-step explanation:

In order to find the answer, we first need to know the slop form.

y=mx+b

In order to find the slope (m), we need to find at least 2 clear points on the graph. Looking at the graph, we can see that one point is (-5, 1) and (0, -1).

We can use either the formula [tex]\frac{y2-y1}{x2-x1}[/tex] or rise over run. In this scenario, looking at the graph and using rise over run will be the fastest way. Starting at point (0, -1), you have to rise 2 and run 5.

In addition, the line is going into infinite value in the second and fourth quadrant. This tells us that the slope is negative. [tex]m=-\frac{2}{5}[/tex].

To find the b value, all we have to do is find the y-value that is on the y-axis. (0, -1), and the answer is -1.

This, gives use the formula [tex]y=-\frac{2}{5}x-1[/tex]

If you want to check your answer, simply plug in a random point on the line into the formula and the equation will be valid.

Round to nearest hundredth (two decimals after decimal):

(Thousandths digit is greater than 5; round up)

The area of a rectangle is 294.4 sq.cm. The length of one side is 16cm. What is the perimeter?
Area = L x w
Perimeter = L + L + W + W

Answers

the perimeter is 68.8cm

Ok so because this is a rectangle the line directly across (paralell) is equal, so if one line is 16cm, the line parallel to that will also be 16. Then the formula for area is LxW we'd plug in the numbers we know to get 294.4[tex]cm^{2}[/tex] =16 x W

then we divide 16 by both sides to make it even to get 18.4cm=W. Now we just plug everything in to the perimeter by doing 16 x 2 + 18.4 x 2 to get

294.4 / 16 = 18.4 = other side length
2 (18.4) x 2 (16) = 68.8cm perimeter

Type the correct number into the ratio tables
