Yvaries inversely with x. if y = 8 and k (the constant of variation) = 19, what is x?
round to the nearest thousandth, if necessary.
-y varies inversely with x, and k (the constant of variation) = 23. what is the value of y when x = 7?
round to the nearest tenth, if necessary.
-y varies inversely with x. when y = 6.7, x = 1. what is the value of k, the constant of inverse variation?
round to the nearest tenth, if necessary.

Part 1)

Part 2)

Part 3)

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form or

Part 1) y varies inversely with x. If y = 8 and k (the constant of variation) = 19, what is x?

we know that

substitute the given values and solve for x

Part 2) y varies inversely with x, and k (the constant of variation) = 23. What is the value of y when x = 7?

we know that

substitute the given values and solve for y

Part 3) y varies inversely with x. When y = 6.7, x = 1. What is the value of k, the constant of inverse variation?

we know that

substitute the given values and solve for k

answer is x<
