Assume that y varies inversely with x. If y = -3 when x = 2.4, what is y when x = 2?

Answer 1

To find the value of y when x = 2, we can use the inverse variation equation.

The inverse variation equation is given by y = k/x, where k is the constant of variation.

To find the value of k, we can use the given information. When y = -3 and x = 2.4, we can substitute these values into the equation:

-3 = k/2.4

Solving for k, we multiply both sides of the equation by 2.4:

k = -3 * 2.4

k = -7.2

Now that we have the value of k, we can substitute it back into the inverse variation equation to find y when x = 2:

y = (-7.2)/2

y = -3.6

#y=1/x#

#y=k1/x#

#-3=k 1/2.4#

#-7.2=k#

#y=k1/2#

#y=-7.2 1/2#

#y=-3.6#

the answer is -3.6.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
