Can a coefficient of a exponent be negative?
Yes, a coefficient of an exponent can be negative. Negative coefficients indicate the opposite direction or opposite effect of positive coefficients in mathematical expressions.
How do you use different techniques to solve linear equations?
There are several techniques to solve linear equations. One common technique is the elimination method, where you eliminate one variable by adding or subtracting equations. Another technique is substitution, where you solve one equation for a variable and substitute it into the other equation. You can also use matrices and row operations to solve linear equations.
What is when two variables are being examined and one variable moves one way and the other variable moves in the opposite direction?
Inverse relationship
Is y equals 2x subtract 3 and 2x subtract 4y equals 8 parallel perpendicular or neither?
y=2x-3 2x-4y=8-4y=-2x+8y=-2/-4x+8/-4y=1/2x-2the equation for slope intercept form is y=mx+bm being the slopeparallel equations would have the same slope (m) andperpendicular equations have opposite reciprocal slopesthe opposite reciprocal of 2 is -1/2the equations are neither parallel or perpendicular.
Is 3x-8y12 and 32x 12y12 parallel or perpendicular?
You are missing either a + or a - in 32x 12y12 You must have meant either 32x+12y12 or 32x-12y12. Also, if you probably meant to compare the two, they should have been equations to describe a line. Probably you meant 3x-8y12=0 and 32x+-12y12=0. Then you could have gotten the slope of the lines by rearranging the equations to the form y=mx+b. m is the slope of the line. If they have the same slope, they would be parallel. If they had opposite slope, they would be perpendicular. In this case, after rearranging the equations, you will find that they have neither the same slope nor opposite slopes; so they are neither parallel nor perpendicular.
What is the key to using the elimination method to find variable terms in the two equations that have equal or opposite coefficients?
Eliminate the variables that have equal coefficients but opposite in sign.x + 2y = 103x - 2y = 14Or you can work to have one of the variables with equal coefficients but opposite in sign such as:3x + 2y = 5x + y = 2 multiply by -2 to both sides3x + 2y = 5-2x - 2y = -4
True or false The key to using the elimination method is to find variable terms in the two equations that have equal or opposite coefficients?
True
Four steps to the elimination method?
There are four steps in an algebraic elimination problem. These steps are: to find a variable with equal or opposite coefficients, if equal then subtract the equations but if opposite then add, solve one variable equation left, and then substitute known variable into other equation and solve. hi
If coefficients aren't equal or opposite can do a little manipulation so that you can still use the elimination method?
True
If coefficients arent equal or opposite you can do a little manipulation so that you can still use the elimination method?
true
Opposite of conservation?

What does the constant variable do?
Variables are not constants. The terms have opposite meaning.
How are inverse operations used to solve multi-step equations?
because you do the opposite
How are the chemical equations for photosynthesis and and aerobic respiration different?
They are opposite to each other .
What are the variables of macroeconomics?
It depends on the way that the subject is modelled as to how many and what are the variables involved. Some models are incomplete and have only a few variables. The smallest model that I know that is comnplete has 19 variables. They are all money flows which are opposite to the value of the goods, services and valuable legal documents that flow in the opposite direction between the same entities.
