Multiplicative VS Additive and Independent/Dependent MIXED 22

Front

What is an additive relationship?

Back

An additive relationship is when two quantities are combined by addition. For example, if you have 3 apples and you buy 2 more, the total is 3 + 2 = 5 apples.

Front

What is a multiplicative relationship?

Back

A multiplicative relationship is when one quantity is multiplied by another. For example, if each CD costs $12 and you buy 4 CDs, the total cost is 12 x 4 = $48.

Front

How do you identify an additive relationship in a graph?

Back

In a graph, an additive relationship shows a straight line with a constant slope, indicating that as one variable increases, the other increases by a fixed amount.

Front

How do you identify a multiplicative relationship in a graph?

Back

In a graph, a multiplicative relationship often shows a curve or an exponential growth pattern, indicating that as one variable increases, the other increases at a rate proportional to its current value.

Front

What equation represents the total cost of 'n' items each costing 'p'?

Back

The equation is c = pn, where 'c' is the total cost, 'p' is the price per item, and 'n' is the number of items.

Front

What is the difference between independent and dependent variables?

Back

An independent variable is the one that is changed or controlled in an experiment, while a dependent variable is the one that is measured or affected.

Front

If 'y' depends on 'x', what type of relationship is this?

Back

This is a dependent relationship, where the value of 'y' changes based on the value of 'x'.

Front

What does it mean if two variables are independent?

Back

If two variables are independent, it means that the change in one variable does not affect the other variable.

Front

Give an example of an additive equation.

Back

An example of an additive equation is x + 5 = 10, where you can find x by subtracting 5 from both sides.

Front

Give an example of a multiplicative equation.

Back

An example of a multiplicative equation is 3x = 12, where you can find x by dividing both sides by 3.
