Instructions: The variables x𝑥 and y𝑦 vary inversely, and y=7𝑦=7 when x=2𝑥=2. Write an equation that relates x𝑥 and y𝑦 and find y𝑦 when x=−6𝑥=−6. Enter any fractions using the forward slash (i.e. “/”; -1/2 is the same as −12−12). Reduce all fractions.Equation: Answer 1 Question 12Solution: When x=−6𝑥=−6, y=

Instructions: If y𝑦 varies inversely as x𝑥 and y=2𝑦=2 when x=8𝑥=8, find y𝑦 when x=2𝑥=2. Write the equation using the given information, then use the equation to solve for y𝑦. Use the forward slash (i.e. "/") for all fractions (e.g. -1/2 is the same as −12−12).

Instructions: y𝑦 varies directly with x𝑥. If y=−4𝑦=−4 when x=2𝑥=2, find y𝑦 when x=−6𝑥=−6. State the equation. Use the forward slash (i.e. "/") for all fractions (e.g. -1/2 is the same as −12−12). Equation: y=𝑦= Solution: y=

Instructions: Assume that y𝑦 varies inversely as x𝑥. If y=8𝑦=8 when x=−2𝑥=−2, find y𝑦 when x=4𝑥=4.y=𝑦= Answer 1 Question 22
