How can you tell if a parabola moves up or down in an equation?
Look at the discriminant, B2 - 4AC, in the quadratic equation. As it goes from negative to positive, the parabola moves in the direction of its small end towards the X-axis. At zero, it touches the X-axis.
What are the rules of multiplying negatives and positives?
positive X positive = positive positive X negative = negative negative X positive = negative negative X negative = positive
When multiplying a negative number by a positive number is the result going to be negative or positive?
The result will always be negative. Positive X Positive = Positive Negative X Negative = Positive Positive X Negative = Negative
What are the rules for multiplying integers?
Positive x Positive =Positive Positive x Negative= Negative Negative x Positive= Negative Negative x Negative =Positive
What number must you add to the following statement to make it true 9 plus x equals 0?
If this is the equation you presented: 9+x=0 then x would have to equal (-9). This is because the negative 9 and the positive 9 cancel out to equal zero. -Owlsrule96
In this equation is X positive negative or zero x plus 9 6?
In the equation x + 9 = 6, x is negative.
Why does the product of an integer multiplied by itself cannot be negative?
There are just three possible cases: Positive integer: positive x positive = positive. Negative integer: negative x negative = positive. Zero: zero x zero = zero.
Is the x axis positive?
No, it is negative, zero and positive.
What does a negative minus a negative equal?
Suppose x and y are two POSITIVE numbers so that -x and -y are negative. Then a negative minus a negative = (-x) - (-y) = -x +y If x > y the answer is negative If x = y the answer is zero If x < y the answer is positive
If x and y are positive integers is x-y always positive?
No, it can also be zero or negative, depending on their magnitudes.
What is signum function?
That is a function defined as: f(x) = -1 if x is negative f(x) = 0 if x is zero f(x) = 1 if x is positive In other words, a function that basically distinguishes whether the input is positive, negative, or zero.
What is the answer to -34 x 0?
The answer is zero. If you multiply any number, no matter if it's negative or positive, by zero the answer will be zero.

When is there no solution possible to an absolute value equation and why?
For example: | x | = -1 Or any other equation where the absolute value of any expression is negative. This doesn't have a solution, because the absolute number of any expression is always positive, or zero, never negative.
Where is -x located?
The notation "-x" typically represents the negative of a variable "x." In terms of a number line, if "x" is a positive value, then "-x" is located at the corresponding position on the left side of zero, indicating a negative value. If "x" is negative, then "-x" would be positive and located to the right of zero. The specific location depends on the value of "x."

Why does Negative times a negative equal a positive?
There are a lot of long examples that help to visualize why a negative times a negative is a positive, but this is just going to be an algebraic proof. Let x = a*b + (-a)*b + (-a)*(-b) If we factor out the (-a) for the second part of the equation, we are left with: x = a*b + (-a)*(b+(-b)) b+(-b) = 0, so the resulting equation is: x = a*b + (-a)*0 Any number times zero is zero, so: x = a*b Next, we go back to the original equation, and factor our the "b" from the first part, leaving: x = (a+(-a))*b + (-a)*(-b) a+(-a) = 0, so: x = 0*b + (-a)*(-b) 0*b = 0, so: x = (-a)*(-b) Now we see that x equals both a*b and (-a)*(-b), meaning: a*b = (-a)*(-b) So the product of 2 negative numbers must be equal the the product of their positive counterparts, i.e., a positive result.
