What else can I help you with?
When using the substitution to solve nonlinear system of equations you should first see if you can one variable if you can one variable in one of the equation in the system?
The general idea is to solve one of the equations for one variable - in terms of the other variable or variables. Then you can substitute the entire expression into another equation or other equations; as a result, if it works you should end up having one less equation, with one less variable.
How is writing an equation to represent a situation involving two variables similar to writing an equation to represent a situation involving only one variable?
An equation with only one variable has only one letter used in it, and that letter is usually an "x" An equation having two variables will have two different letters representing them, usually the letters "x" and "y" The first type could be the equation 5x^3 - 3x^2 + 6x - 50 = 0 The second type could be (x +y)^2 - 7x^3 + 12x = 58.8 1 equations with only 1 variable are usually much easier to solve than an equation with 2 variables, and you cannot solve the latter unless you have two separate equations containing the two variables.
Can you solve 3x2-3y2-48 equals 0?
No! To get the solution number of unknown variables must be equal to the number of equations. [For example, In this case, two variables (x and y) are involved but only one equation is given. so, we need one more equation having same two variables to get the solution.] If there is no other equation then value of any one of the variables involved (x or y) must be given to ind the value of the other unknown variable.
Do Equations Having More Than One Variable?
Equations can have as many variables as you want, however to solve an equation you need as many equations as there are unknowns. E.g. in an equation with x & y as the unknowns you would need two different equations containing x and/or y to solve them
What is one of the values of a variable which divides the distribution of the variables into four groups having equal frequencies?
quartile
Anova depends on having independent variables describe an abuse that might occur by having dependent variables?
there are three kinds of variables.a variable must be a situation,condition or a factor1.change or manipulated variables.-are the variables that are being tested or changed.2.constant variables.-are the variables that you are not intended to test or study,or the variables to be kept constant.3.responding variables.-are the results of the maipulated variables.
How can you use proportions to solve equations with variables on both sides?
A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
What is the difference between identifiers and variables in C lang?
a variable having the datattype and name, an identifier is the name of the variable for example int x; here int x; is the variable x is the identifier
What is one of the values of a variable which divides the distribution of the variables into three groups having equal frequencies?
A tertile or tercile.
Why can you not draw a conclusion about the effect of one variable - in an investigation when the other key variables are not controlled?
Because there is no way to know what effects the other key variables are having on outcome. So, there is no way to evaluate any one variable, or its effects on outcome.
How do solve for the variable over a number in a linear equation?
Well a variable in a number in a linear equation is basically the variable divided by a number. So if you have x over 10, it is basically x times 1/10. You can solve by having either another equation and use either point slope or y=mx+b.
A dichotomous variable is?
Dichotomous means "having only two possible values." Examples of dichotomous variables are yes/no or male/female.
