$40+105+x=180\\
x=35$

The sum of two sides must be greater than the third side.
It can't be 5 because $5+5=10\not>12$ .
It can't be 7 because $5+7=12\not>12$ .
It can't be 17 because $5+12=17\not>17$ .
So it's 12.

Suppose that x and y vary inversely, and x = 12 when y = 8 . Write the function that models the inverse variation.

Alja [10]

Answer:

$y=\frac{96}{x}$

Step-by-step explanation:

So when x and y, vary inversely, it means that the product of x and y will remain constant such that: $xy=c$ . This means that the function can be defined as $y=\frac{c}{x}$ by dividing both sides by x. In this case x=12, and y=8, this means the constant is equal to 12 * 8 which is 96. So we have the equation: $xy = 96$ , which can be defined as $y=\frac{96}{x}$
