Front

Write the equation of the line given the slope and y-intercept.

Back

The equation of the line is y=(3/5)x-1.

Front

What property is demonstrated by the equation (30 + 20) + 60 = 30 + (20 + 60)?

Back

This demonstrates the Associative Property of Addition.

Front

Simplify the expression √-108.

Back

The simplified form is 6i√3.

Front

What are the dimensions of a matrix with 4 rows and 3 columns?

Back

The dimensions of the matrix A are 4x3.

Front

Evaluate the determinant of the matrix that results in -21.

Back

The determinant of the matrix is -21.

Front

What is the formula for the slope-intercept form of a line?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

Define the Associative Property of Addition.

Back

The Associative Property of Addition states that the way in which numbers are grouped in addition does not change their sum.

Front

What is the imaginary unit 'i'?

Back

The imaginary unit 'i' is defined as √-1.

Front

How do you find the determinant of a 2x2 matrix?

Back

For a 2x2 matrix [[a, b], [c, d]], the determinant is ad - bc.

Front

What is the Commutative Property of Addition?

Back

The Commutative Property of Addition states that changing the order of the addends does not change the sum.
