For the inverse variation equation xy = k, what is the constant of variation, k, when x = 7 and y = 3? 3/7 7/3 10 21

Elza [17]

Hello there,

So by using the formula xy=k just plug in both x and y.

So this would be (7)(3)=k

Which means 21=k

Hope this helped!

Value of r is -4

Step-by-step explanation:

We are given points (-1,-6) and (0,r) on line and slope of line is -2. We need to find value of r.

Using slope formula when two points are given:

$Slope=\frac{y_2-y_1}{x_2-x_1}$

Where $x_1=-1,\,\,y_1=-6,\,\,x_2=0,\,\,y_2=r$

Putting values:

$2=\frac{r-(-6)}{0-(-1)} \\2=\frac{r+6}{0+1} \\2=\frac{r+6}{1} \\2=r+6$

Adding -6 on both sides:

$2-6=r\\-4=r$

So, Value of r is -4

Agata [3.3K]

The median thickness of the entire glacier is calculated with the arranging the given dimensions of the thickness from least to highest.
29, 34, 35, 36, 38, 40, 41, 43, 44, 46
The middle tern is the 5th and 6th terms which are equal to 38 and 40. Average of this cool is still 39.
