Why do you use cubic graphs?
There are variables that have a cubic relationship: for example, the side of a cube and its mass.
What is a combination of variables and one operation?
an expression
What equation that has variables on each side and has a solution of -2?
There are an infinite number of such equations.Here's one of them:2x + 6 = -x(Since the solution is only 1 number, theequation can only have 1 variable.)
What is An expression that consists of one or more variables?
Polynomial
Can you find the length of one side with the hypotenuse and the right angle?
No. You need either another angle or the length of another side. For example, to solve a2 +b2=c2 (the formula for a right triangle, in which c is the hypotenuse) you must have values for 2 variables to solve for the third.
How do you solve variables on both sides?
1) distribute 2) combine like terms 3) get all variables on one side 4) get contsants to the other side 5) find x
How do you change slope form to standard form?
Just leave the constant at one side and the terms with variables at the other side.
-3r - 8 equals -5r plus 12?
What you want to do is to try and get all the variables on one side by adding/subtracting. Then get the numbers on the other side and solve.
What makes equation a true statement?
A feasible solution, which when applied means that all the variables etc... on one side of the equation equal to whatever is on the other side of the equation.
How do you solve 5t-5 equals 5t plus 7?
You don't for t, as gathering your coefficient variables together = 0 5t - 5 = 5t + 7 now, subtracting 5t from either side to get the variables on one side of the equation renders this. - 5 does not = 7
What is an affine variety?
An affine variety is a set of points in n-dimensional space which satisfy a set of equations which have a polynomial of n variables on one side and a zero on the other side.
How do you solve an equation with two different variables on one side?
You decide to solve for one of the variables, for example, for "y". What exactly you do would depend on how the variables are related. For example, if you have:x + y = 5 and you want to solve for "y", you subtract "x" on both sides. If you have a product, such as: xy = 10 you divide both sides by "x".
What are independent variables?
Independent variables are factors in a study that are manipulated or controlled by the researcher in order to observe their effect on the dependent variable. They are variables that are believed to influence the outcome of an experiment or study.
How to solve equations with variable on each side?
There are different techniques, depending on the specific situation. In the simplest case, you transfer all the variables to one side. Here is an example: 4x = 2x + 16 Subtract "2x" on each side: 2x = 16 Now you have a single variable, on only one side.
Is eliminating variables from equations equal to find the value of the variables?
No, but eliminating variables is one of several ways to find the value of variables in a system of equations.
What is the answer to 2x - 3 equals 10x - 99?
2x-3 = 10x-99 start by moving the terms with variables (x) on one side of the equal sign, and the constants (regular number, with no variables) to the other side. Do this by addition and subtraction. 2x-3 = 10x-99 +99 +99 now you have 2x +96= 10x now get both of the variables on the right side 2x+96 = 10x -2x -2x now you have 96 = 8x now solve for x by dividing each side by 8 96/8 = 8x/8 x= 12
How do you write an equation that works in forward and reverse?
You can write an equation that works in forward and reverse by setting the same variables on either side. Alternatively you can set offsetting variables on each side which will also create the same results.
