Wait, How did you get here? who are you people?
serioulsy, how did you get here? I guess here's 100 points? just- just take it and please leave. your not supposed to be back here. don't come back to this nonexistent catagory.
3x + 2y = 11
-4x -6y = -3
what is the equation of a standard form of a line?
Ax + By = C
What is the parent function of a square root?
f(x) = √ x
(m2 + 2) (m - 1)
m3 - m2 + 2m - 2
Uhhh- your not leaving. uhhh... well then. I guess I'll give you an unsolvable question. who was My middle-school math teacher?
Mrs. Caton! Ha! bet you didn't guess that!
how do you do substitution?
you solve one of the equations for either of the variables, then you substitute the equation for the variable, into the same variable of the other equation (Example: you solved Y, so you put Y's equation into Y's place in the other equation.), then you plug the solution of this equation into one of the original equations.
where do the two lines intercept?
y = 5x - 3
y = 5x + 1
they are parallel, because they have the same x, and as such, do not intercept each other.
what is the parent function of a Linear Equation?
f(x) = x
what does FOIL stand for?
First, Outer, Inner, Last.
what is the capital of the country of Liechtenstein?
The City of Vaduz.
Graphing, Elimination, and Substitution
what is the formula for a slope-intercept linear equation
y = mx + b
what is the parent function of an absolute value?
f(x) = |x|
(b3 + 3) (b - 2)
b3 - 2b3 + 3b - 6
What form of Government is the country of Monaco?
Monaco is a Monarchy, more specifically, a principality.
How do you do elimination?
you multiply one of the two equations by a number that allows for one of the variables to be eliminated when both equations are added together. then you can solve for the remaining variable, an that will allow you to solve for the final variable.
what is the point-slope form of a line?
y-y1 = m (x-x1)
What is the name of the line created by a Quadratic Equation?
The Parabola
A4 B5 C7 D8 = A5 B4 C7 E3
A4 B4 C7
This is the hardest one. what country is the 3rd smallest country in the world?
it is Nauru. Nauru is an island nation in the southwestern Pacific Ocean. Bet you didn't know that, huh?
