Question

Determine whether the relation represents y as a function of x. 5x + 8y = 40 • This relation is a function because there are values of x that corr • This relation is a function because there is only one value of y fo • This relation is not a function because there are values of x that O This relation is not a function because there is only one value of y

Answer 1

Explanation:

5x + 8y = 40

that can be transformed into

8y = -5x + 40

y = (-5x + 40)/8

so, yes, this is a regular function, as there is exactly one value of y associated to each possible value of x.
