## What does jointly mean in math?

When we say z is jointly proportional to a set of variables, it means that z is directly proportional to each variable taken one at a time. If z varies jointly with respect to x and y, the equation will be of the form z = kxy (where k is a constant).

### What is the difference between joint and combined variation?

Joint variation is similar to direct variation. It involves two or more variables, such as y=k(xz). Combined variation combines direct and inverse variation, y=kx/z.

**What does it mean when a variable varies jointly?**

Joint variation describes a situation where one variable depends on two (or more) other variables, and varies directly as each of them when the others are held constant. We say z varies jointly as x and y if. z=kxy. for some constant k.

**What is the difference between direct and joint variation?**

The value of y varies directly with x, y is directly proportional to x. k is called the constant of proportionality, and is typically positive. Special Case: Direct Square variation: y=k{{x}^{2}}….Direct, Inverse, Joint and Combined Variation.

## How do you write varies jointly?

Equation for a joint variation is X = KYZ where K is constant. One variable quantity is said to vary jointly as a number of other variable quantities, when it varies directly as their product. If the variable A varies directly as the product of the variables B, C and D, i.e., if.

### What is combined variation in math?

Combined variation describes a situation where a variable depends on two (or more) other variables, and varies directly with some of them and varies inversely with others (when the rest of the variables are held constant).

**How will you describe a joint relationship of quantities?**

One variable quantity is said to vary jointly as a number of other variable quantities, when it varies directly as their product. If the variable A varies directly as the product of the variables B, C and D, i.e., if. A ∝ BCD or A = kBCD (k = constant ), then A varies jointly as B, C and D.

**What is direct inverse and joint variation?**

Joint variation occurs when a variable varies directly or inversely with multiple variables. For instance, if x varies directly with both y and z , we have x=kyz x = k y z . If x varies directly with y and inversely with z , we have x=kyz x = k y z .

## What is direct variation?

Definition of direct variation 1 : mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other. 2 : an equation or function expressing direct variation — compare inverse variation.
