What is the discriminant and how is it used to solve equations using the quadratic formula?
It is not to solve so much as to see the number of solutions and whether there is a real solution to the equation. b2 - 4(a)(c) A positive answer = two real solutions. A negative answer = no real solution ( complex solution i ) If zero as the answer there is one real solution.
Which equation has a solution of -4?
There are an infinite number of equations with this solution, eg x = 6 - 10; x = 45678 - 45682; x squared = 16 etc etc
How do you solve this graphing equation y plus x equals 6?
The solution consists of the infinite number of points on the line which is defined by y + x = 6.
How do you solve for x if the problem is 3x plus 20?
You haven't given the solution to the equation ! 3x + 20 = ? If you have the number for the question-mark - you can find the value of x ! For example in the equation 3x + 20 = 50... the value of x is 10.
What is the solution for 9.4605284 x 1012?
There can be no solution to a number. That is like asking what is the solution to 3!
Explain how you an determine if the number is a solution of an equation?
Substitute the number in the equation. If the resulting statement is true the number is a solution to the equation.
How do you determine if a number is a solution of an equation?
plug your answer it to the original question
Using the Kw equation how is it possible to determine whether an aqueous solution is acidic basic or neutral?
When you combine the Kw equation with the total mass of the solution, you will get a number. If the number is above 60, it is a acid, it is below 75, it is a base and if your number is between 60 and 75, it is neutral.
What is A number that makes a equation true?
The solution set is the answers that make an equation true. So I would call it the solution.
What does it mean when it says determine whether the given value of the variable is a solution?
I'm going to assume you have an equation to go with your variable? It means "Check if this number works" What to do is put the given value into the equation instead of the variable and see if the result is true - if it is you have a solution, if not you don't. I'll make one up as a demo: Equation : a + 4 = 7 is a = 2 a solution? a+4=7 2+4=7 6=7 (FALSE!) No this given value is not a solution.
A value that makes an equation true?
Any number that makes an equation true is a 'solution of an equation'. it is a solution
Number that makes an equation true?
A number that makes an equation true is its solution.
Math tell whether the ordered pair is a solution of the equation?
The idea is to replace one variable in the equation by the first number in the ordered pair, the other variable with the second number in the ordered pair, do the calculations, and see whether the resulting expressions are indeed equal.
What is the word for a number that makes an equation true?
Solution. A solution of an equation is a number that satisfy the equation. This means that if you replace this number on the equation and check it, the equation will be true. When you solve an equation you can find some roots, but not all of them satisfy the equation. Thus always check your answers after resolving your equation, and eliminate as solution the answers that don't make the equation true or undefined.
When can you say that a number is called a solution in algebraic expression?
An algebraic equation or inequality can have a solution, an algebraic expression cannot. If substituting a number in place of a variable results in the equation or inequality being a true statement, then that number is a solution of the equation or inequality.
The number that makes an equation true?
The solution
What is the number that can replace a variable in an equation to make it a true equation?
what is the number that can replace a variable in a equation to make it a true equation? 8 letters this is not a good answer go look 4 a notha one
