Which symbol creates a true sentence when x equals 8?

2 answers:

8 0

To solve this equation, first replace x with its value, 8. Find 7^2 (49) and 8-4 (4). Then find 4^2 (16), and add 49 and 16 together, which is 65. Because 65 is greater than 55 by 10, the correct answer is b.

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