How do you find a ratio that is not proportional?
u find the common denominator
How do you find the value of an algebraic expression?
Take the value of each variable in the expression and replace the variable by its value. Then do the math!
How do you solve simultanious equations?
By eliminating or substituting one of the variables in the two equations in order to find the value of the other variable. When this variable is found then substitute its value into the original equations in order to find the value of the other variable.
Why is it important to be able to solve for the variable in a formula?
Solving for one variable makes it easy to put in a value for the other variables, and find a value for the first variable.
Is there a calculator that can find the value of x?
No, because 'x' is a variable.
How do you find a ratio that is not proportional?

How do you solve problems with direct proportion?
find the ratio . ratio should be samecheck that if A increases value of B also incresase. if our ques holds both the property it means that it is direct proportional .
What is the definition for direct proportional?
Direct proportional describes a relationship between two variables where an increase in one variable leads to a proportional increase in the other variable. This relationship is typically represented by a straight line when graphed.
What is the result of substituting a value for a variable in a function?
To find the value of the other variable
How do you find the value of a variable of a trapezoid?

What is a characteristics of a dependent variable?
The variable that depens on a number or anther variable to find it's value.
How do you find the value of a ratio?

Explain how to find restrictions on the variable in a rational equation?
Substitute the variable in the denominator for a value that will make the denominator have a value of 0 or an imaginary number
What is the variable used to predict another variable called?
It is called the independent variable. For example if you are trying to find y: y = x+1 X is the independent variable, and Y is the dependent variable. The value of Y, depends on the value of X.
