A collection of flashcards to help students review key concepts and formulations from the B.E.S.T. Algebra 1 EOC assessment test items.

What is the formula for earned run average (A) in baseball?

A = N 9E, where E is the number of earned runs and N is the number of innings pitched.

Which formula is used to find the final amount under compound interest?

A = P (1 + r/n)^(nt), where P = principal, r = rate, n = number of times compounded, t = time.

What does the term 'linear function' imply in mathematical contexts?

A function that graphs a straight line.

How is the slope of a line identified in slope-intercept form?

The number in front of x in the equation y = mx + b.

What does an inequality represent graphically?

A range of values that satisfy the inequality condition.

What is one key characteristic of exponential decay functions?

The function decreases over time, typically modeled as y = a(1 - r)^t.

For a system of equations, what must be true for the equations to have a solution?

The equations must intersect at some point on a graph.

How is profit typically represented in an equation?

Profit = Revenue - Cost.

What does 'quadratic function' describe in algebra?

A function that can be expressed in the form y = ax^2 + bx + c, where a ≠ 0.

What does a system of inequalities represent?

Multiple conditions that define a region in a graph where solutions lie.

What is a piecewise function?

A function defined by multiple sub-functions, each applying to a specific interval of the domain.

How can you evaluate the equation of a line?

By plugging in values for x to find corresponding values of y.

What is the purpose of a table of values in relation to a function?

To provide specific input-output pairs that represent the function.
