What are the possible solutions for a system of equations?
The system of equations can have zero solutions, one solution, two solutions, any finite number of solutions, or an infinite number of solutions. If it is a system of LINEAR equations, then the only possibilities are zero solutions, one solution, and an infinite number of solutions. With linear equations, think of each equation describing a straight line. The solution to the system of equations will be where these lines intersect (a point). If they do not intersect at all (or maybe two of the lines intersect, and the third one doesn't) then there is no solution. If the equations describe the same line, then there will be infinite solutions (every point on the line satisfies both equations). If the system of equations came from a real world problem (like solving for currents or voltages in different parts of a circuit) then there should be a solution, if the equations were chosen properly.
What is a proof in calculus?
A proof in calculus is when it will make a statement, such as: If y=cos3x, then y'''=18sin3x. Then it will tell you to do a proof. This means you have to solve the equation step by step, coming to the solution, which should be the same as in the statement. If you do come to the same answer as in the statement, then you just correctly did a calculus proof.
What should be added to both sides of the equation x plus 7 equal -4?
3
I need An answer for 2x square -3x-2 0?
there is no problem with this quadratic equation it's 2x square - 3x -2 = 0 I need an answer. where it says square there should be a little 2 at the top corner of the 2x to make it 2x square thanks If you can't factor it easily then use the quadratic equation: The two solutions are: 2 & -.5
What should be added to both sides of this equation to solve for the variable 18 plus y equals 32?
You add -18... 18 + y = 32 18 + y + (-18) = 32 + (-18) y = 14
Once you have come up with an answer to the solution you should return to the equation and make sure your answer satisfies it A True or B false?
As long as time permits you defiantly should.
According to the problemsolving strategies you've learned so far once you have come up with a solution to the problem you should return to the equation and make sure your answer satisfies it?
true
How do you show that a wave function is a solution to the time- independent Schrodinger equation for a simple harmonic oscillator?
You should substitute your solution in the equation. If the solution is correct you will receive equality. Otherwise your solution is wrong.
what number should be placed in the blank to make the equation balanced?
A solution.
What are some steps after coming up with a solution?
If you mean for a math problem, after coming up with a solution you should usually check the solution in the original equation, to be safe.
When both variables cancel in a linear equation leaving you with a true statement. How should this be interpereted?
It means that whatever you have substituted is the solution of the given linear equation. Or you have substituted the equation in itself.
What tasks should you perform if you discover a new problem when testing the solution?
You document the attempted solution You return to the beginning of the troubleshooting process
How do you check your solution with inequalities?
1) Replace the inequality signs in the solution and in the original question with = signs. Substitute the solution inn the question: it should make it true. 2) (Back to the inequalities) Pick another number that satisfies the solution inequality - e.g. if x>2, pick 5. Substitute this into the original inequality: if it makes it true, then you are good to go!
What is the solution to x2 plus 7x plus 14 equals 0?
You should be able to look at this equation, or use the discriminant and know that there are no real roots.
If conductivity solution is frozen will it change the conductivity?
Conductivity of frozen solution will decrease tremendously, as iones will be immobile in frozen solution. However, upon defrost, the conductivity should return to standard value, if salt has not percititated out of solution irreversibly, which is not ususally the case with conductivity standard solutions.
How many gallons of a 10 percent ammonia solution should be mixed with 50 gallons of a 30 percent ammonia solution to make a 15 percent ammonia solution?
Make an equation: x(.10) = 50gal(.15) Solve algebraically: x = 75 gal
What is the difference between a number model and a number sentence?
A number sentence has a letter as its solution while a number model has the solution. I remember this by thinking of a number model as a model of what the full equation should be and a number sentence being the opposite of that.
