constant - ANSWER- a value that does not change
factor - ANSWER- a number or expression that is multiplied by another number or
expression to get a product
monomial - ANSWER- a number or a product of numbers and variables with whole-
number exponents, or a polynomial with one term
polynomial - ANSWER- a monomial or a sum or difference of monomials
consistent system - ANSWER- a system of equations or inequalities that has at least
one solution
dependent system - ANSWER- a system of equations that has infinitely many solutions
elimination method - ANSWER- a method used to solve systems of equations in which
one variable is eliminated by adding or subtracting two equations of the system
inconsistent system - ANSWER- a system of equations or inequalities that has no
solution
independent system - ANSWER- a system of equations that has exactly one solution
substitution method - ANSWER- A method used to solve systems of equations by
solving an equation for one variable and substituting the resulting expression into the
other equation(s)
system of linear equations - ANSWER- a system of equations in which all of the
equations are linear
correlation - ANSWER- a measure of the strength an direction of the relationship
between two variables or data sets
correlation coefficient - ANSWER- a number r greater than or equal to -1 and less than
or equal to 1, that describes how closely the points in a scatter plot cluster around the
line of best fit.
linear regression - ANSWER- a statistical method used to fit a linear model to a given
data set
, residual - ANSWER- the signed vertical distance between a data point and a line of fit
X-Intercept - ANSWER- The x-coordinate(s) of the point(s) where a graph intersects the
x-axis.
Y-Intercept - ANSWER- The y-coordinate(s) of the point(s) where a graph intersects the
y-axis.
Linear Function - ANSWER- A function that can be written in the form y=mx+b, where x
is the independent variable and m and b are real numbers. Its graph is a line.
Rate - ANSWER- A ratio that compares two quantities measured in different units.
Rate of Change - ANSWER- A ratio that compares the amount of change in a
dependent variable to the amount of change in an independent variable.
Slope - ANSWER- A measure of the steepness of a line.
Exponent - ANSWER- The number that indicates how many times the base in a power
is used as a factor.
Exponential Expressions - ANSWER- An algebraic expression in which the variable is in
an exponent with a fixed number as the base.
Exponential Function - ANSWER- A function in the form f(x)=ab^x where a and b are
real numbers, a does not equal zero, b>0, and b does not equal 1.
Perfect Square - ANSWER- A number whose positive square root is a whole number.
Exponential Growth - ANSWER- An exponential function in the form y=a(1+r)^t, where r
is the rate of growth, a is the initial amount and t is the time.
Exponential Decay - ANSWER- An exponential function in this form, where r is the rate
of decay, a is the initial amount and t is the time.
Base - ANSWER- The number in a power that is used as a factor.
Half-life - ANSWER- The half-life of a substance is the time it takes for one-half of the
substance to decay into another substance.
arithmetic sequence - ANSWER- A sequence whose successive terms differ by the
same nonzero number, called the "common difference".
common difference - ANSWER- In an arithmetic sequence, the nonzero constant
difference of any term and the previous term.
