When does the nonlinear equation becomes linear equation?
A linear equation is defined as an equation that contains only the first power of the unknown quantity. For example, 5x - 3 = 7 where "x" is the unknown quantity is a linear equation. If an equation contains an unknown quantity having a higher power than 1, then the equation ceases to be a linear equation. For example, 3x2 + 5x + 7 = 0 is a non linear equation known as a quadratic equation, because the unknown quantity "x" has a power of 2. Similarly, equations containing unknowns with higher powers such as x3, x7, x12 are all non linear equations.
10 examples of linear equation in one unknown?
yea!
What is the highest exponet of the leading variable in a linear equation?
A linear equation contains only the first power of the unknown quantity. Thus, 5x - 3 = 7 and x/6 = 4 are both linear equations.
What is 15-2n equals 6-n?
It is a linear equation in one unknown variable, n.
How do you graph a linear equation with a fraction in it?
You calculate the coordinates using a fraction!

What is external calibration and is it the same as the manual calibration of equipment?
Well, external calibration is a method used in analytical chemistry to determine the concentration of an unknown analyte. In essence, you take known concentrations of the analyte and plot it on an absorbance or transmittance graph to get a linear plot. And then you take that linear equation and plug in the absorbance or transmittance value received from the unknown solution and get the concentration. An example of this is if you want to find out the amount of calcium in a vitamin tablet. Dissolve the vitamin tablet and test the solution to get an absorbance value. Then test by the same method various concentrations of a calcium solution, plot this on a graph of absorbance vs. concentration and there yah go.
How do you figure out if an equation is a linear equation?
An equation is linear if the highest power of the unknown in the equation is 1for example an equation with just a variable to the power one such as x, y and so on is linear but one with x2, y2 and above is not linear

What is the answer for x-2y equals 2?
It is not possible to solve one linear equation in two unknown variables. Another, independent equation is required.
System of linear equation in one unknown?
A system of linear equations that has one unknown is a set of equations that all depend on the same variable. An example is y = 1 + 3x and y = 4 + 7x.
