Question

In the equation where Robin converts x dollars into y kuna, which expression is the independent variable?

a) x
b) y
c) "Robin converts"
d) "dollars into y kuna"

Answer 1

In the equation converting x dollars to y kuna, the independent variable is a) x. The independent variable can be chosen freely, and it determines the value of the dependent variable, y.

Step-by-step explanation:

In the context of the equation where Robin converts x dollars into y kuna, the independent variable is a) x while the dependent variable is y.

The independent variable is a value you can choose freely, and the dependent variable is what you calculate or determine based on the independent variable.

An example similar to this situation is when you use a variable such as the number of hours Svetlana tutors, represented by x, to determine how much she earns, represented by y. Here, you choose a value for x, the number of hours, and solve for y, the amount earned, which depends on the chosen number of hours.
