Explain how to find restrictions on the variable in a rational equation?
Substitute the variable in the denominator for a value that will make the denominator have a value of 0 or an imaginary number
How do you know the opposites and absolute values of integers?
opposites: if it is a negative, make it a positive. if it is a positive, make it a negative absolute value: take the number without any sign. if it is negative, make it positive. if it is positive, keep it as a positive,
What do you need to do to the inequality sign if you multiply or divide both sides of an inequality by a negative number?
Leave it alone. You cannot make an inequality into an equality by multiplying both sides of the inequation by the same number. If instead of the inequality sign you are using a lesser or greater than sign, however, you will need to reverse it if you multiply both sides by the same negative number, e.g. 10>4. If you multiply both sides by -2, you need to change the > into a <, so -20<-8
If the factors of a polynomial are x - 4 and x - 5 what values of x make that polynomial 0?
4 and 5 -4 and -8
What primary colors make grey?
None--- Gray is a value, not a color/hue.
What is a value or values that make an inequality true?
a solution of inequality
A value or values that make an equation true?
a solution
Find all integer values of x that make the equation or inequality true x2 equals 9?
that would be limited to 3 and -3 for values of x
What is any and all values of the variable that satisfies an equation inequality system of equations or system of inequalities?
They make up the solution set.
How to graph y - x plus 3?
I suggest that you:* Solve the equation for variable "y". * Make a table of values, by calculating the value of "y" for different values of "x". * Plot the points * Join them by lines
What is an inequality for all the possible values of 6 and 7?
There is only one possible value and so the question does not make sense.
What is the goal of solving an equation with one variable?
The goal is to find what value or values the variable may have, to make the equation true.
How can you answer this equation for an addition equation like 2 x equals 5 how many values will make the equation true?
only one value will make the equation true: 2x = 5 x=5/2 x=2.5
How many different values for x make the equation x equals 5 true?
One, the value five.
What is x in the sum 9x plus 12 equals?
A variable like "x" can have any value. If you have a complete equation, like 9x + 12 = 100, a specific value of x will make the equation true; other values will make it false. But here, you don't have an equation, so any value will do for x.
What is the solution to the equation?
It is the set of values for all the variables in the equation which make the equation true.
What is the difference between an inequality and an equation?
An equation is a statement, such as 2+2=4, and an inequality is an equation that does not make sense, or one that isn't true, such as 2+2=5. --------------------------------------------------- The person who answered above me is half right, half wrong. An inequality is actually NOT an equation that doesn't make sense or isn't true. An inequality has a variable in it. It's similar to an equation yet isn't exactly an equation. It compares numbers to each other. For example, a + 4 > 19. a + 4 > 19 is an inequality. They are different because an inequality doesn't have an equal sign so it can't be solved. An equation adds, subtracts, multiplies, or divides and it has an equal sign. Therefore, it can be solved. An example of an equation IS 2 + 2 = 4,14-12=2, 100/10=10, or 4x4=16.
