Suppose that y varies inversely with x. Use the information to find k, and then choose the equation of variation. x = 2.5 when y = 100.

Answer:constant of variation(k) is, 250.Step-by-step explanation:The inverse variation says that:then, the equation is in the form of :        ....[1] where, k is the constant of variationAs per the statement:Suppose that y varies inversely with x.then,by definition of inverse variation we have;When x = 2.5 and y = 100 thenSubstitute these in [1] we have;Multiply 2.5 both sides we have;ork = 250⇒Therefore, the constant of variation is, 250 and the equation we get Read more on Brainly.com - explanation:
