What is a geometric sequence?

Back

A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.

Front

What is the common ratio in a geometric sequence?

Back

The common ratio is the factor by which we multiply each term to get the next term in a geometric sequence.

How do you determine the domain of a function from a graph?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined, typically represented as a set of numbers.

Front

What does the inequality -9 < x ≤ 2 represent?

Back

This inequality indicates that x can take any value greater than -9 and up to and including 2.

Front

What does it mean for a value to vary directly with another?

Back

If y varies directly with x, it means that y = kx for some constant k, meaning as x increases, y increases proportionally.

Front

If y = kx and x = 3 gives y = 21, what is k?

Back

k = 21/3 = 7.

Front

How do you find the slope of a line given its equation in standard form?

Back

To find the slope from the equation Ax + By = C, rearrange it to slope-intercept form (y = mx + b) where m is the slope.

Front

What is the slope of the line represented by 5x - 12y = 24?

Back

The slope is 5/12.

Front

What is an arithmetic sequence?

Back

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant, known as the common difference.

Front

What is the common difference in an arithmetic sequence?

Back

The common difference is the fixed amount added to each term to get the next term in an arithmetic sequence.
