I’ll give you the crown and a lot of points please help with all of them

stiks02 [169]

Answer:

5) a

6) a

7) b

8) d

9) a

10) b

11) c

12) a

Step-by-step explanation:

When it asks for range it is asking for the y values so when you plug in numbers such as 0,1,2 into the equation the y values you get are {0,90,180..}

Overall slope can be found by taking the x and y values of the two given points.

((y value of the second point)-(y value of the first point))/((x value of the second point)-(x value of the first point))

Using (1,2) and (-2, 5) you can do this by plugin in the numbers (5-2)/(-2-1)

So the slope will be 3/-3 = -1

Once you find the slope you can use this to find the equation of a line by pluging in values into y=mx + b

m = slope

y = use this from the points given

x = use this from the points given

Maddy lleva un bote con bebida para deportistas; el bote de 5 55 litros pesa 7 , 5 kg 7,5 kg7, comma, 5, start text, space, k, g

Kaylis [27]

Answer: $3\ kilograms$

Step-by-step explanation:

It is important to remember that, by definition, proportional relationships have the following form:

$y=kx$

Where "k" is the constant of proportionality.

We know that Maddy assume that the relation between the volume and the weight is proportional.

Then, let be "V" the volume in liters and "w" the weight in kilograms.

We can write the following equation:

$V=kw$

So, if the boat of 555 liters weights 7.5 kilograms, we can find "k":

$555 =k(7)\\\\k=\frac{555}{7}\\\\k=74$

In order to solve the exercise, substitute the value of "k" and $V=222$ into the equation and solve for "w". Then:

$222=(74)w\\\\\frac{222}{74}=w\\\\w=3$
