The points a, b, c, and d are on a number line, not necessarily in that order. if the distance between a and b is 18 and the distance between c and d is 8, what is the distance between b and d?

  insufficient information

Step-by-step explanation:

If the order of the points is unknown, the distances AB and CD imply no particular distance for BD.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
