Linear Equations & Inequalities
This is the number of solutions 4x + 2 = 2(x + 1) has.
What is infinite?
This is the general formula of a line.
What is y = mx+b?
This is the minimum number of equations you need to solve a system with two variables.
What is 2?
This term refers to the highest power present in the polynomial.
What is the degree?
The value under the radical.
What is flip the greater than/less than sign?
If you have the formula y = mx + b, this is the y-intercept.
What is (0, b)?
This method for solving systems of equations by first manipulating one equation so a variable is by itself, then plugging this value into the other equation for the variable.
What is substitution?
This is the factored form of this polynomial: x2+x
What is x(x+1)?
A negative radicand means that the number as a whole is this term, represented by the letter i.
What is imaginary?
How many solutions does 2 + x < 2x < x - 3 have?
What is none?
If you have the formula y = mx + b, this is the x-intercept.
What is (-b/m, 0)?
What is x = 3, y = 6?
This is the expanded form of this polynomial: (x+4)2
What is x2+8x+16?
When multiplying radical expressions, simply do this.
What is multiply the radicands?
This is the solution to 2x + 1 + 2(1 - 3x) = -5
What is 2?
The change in y over the change in x.
What is the slope?
These are the steps in the elimination method of solving systems. (Hint: start by manipulating one equation so that one variable has the same constant as the other equation)
What is manipulating one equation so that one variable has the same constant as the other equation, subtracting (or adding) the equations, solving for the remaining variable, then finding the other variable by plugging the value for the first into an equation?
This is the factored form of this polynomial: 2x2 - 5x - 6
What is (2x+1)(x-3)?
When this occurs, you can add and subtract radical expressions.
What is having the same radicand?
This is the solution to -2x + 4 < x - 6 + 2x
What is x > 2 (or 2 < x)?
The highest or lowest point of a polynomial.
What is a vertex?
This is the solution for: 2x + y = 10, 3x - 2y = 22
What is x = 6, y = -2?
This is the Quadratic Formula.
This is how you simplify radical expressions.
What is dividing the radicand by a perfect square, then placing the square root outside the radical?
