What is a conversion factor?

• Rates that have the same unit rate

  6 miles in 3 hours and 4 miles in 2 hours

• Two ratios that describe the same relationship

  2 : 3 and 4 : 6

• A rate that equals 1; A conversion factor is used to convert units.

What is a ratio?

• A comparison of two quantities; The ratio of a to b can be written as a : b. Ratios can be part-to-part, part-to-whole, or whole-to-part comparisons.

• A ratio of two quantities using different units You read 3 books every 2 weeks.

• A process used to decide which conversion factor will produce the appropriate units

• A table used to find and organize equivalent ratios

What is a dependent variable?

• The variable that represents the output values of a function The equation y = 8x represents the amount of money y (in dollars) you earn after x hours of work. The variable y is the dependent variable.

• A mathematical sentence that uses an equal sign, =, to show that two expressions are equal 4x = 16, a + 7 = 21

• The variable that represents the input values of a function The equation y = 8x represents the amount of money y (in dollars) you earn after x hours of work. The variable x is the independent variable.

• An equation that represents two quantities that change in relationship to one another y = 2x, y = 4x − 3

• A mathematical sentence that uses an equal sign, =, to show that two expressions are equal 4x = 16, a + 7 = 21

• A value that makes an equation true 6 is the solution of the equation x − 4 = 2

What is an independent variable?

• A mathematical sentence without an equal sign.

• Determining the value of a numerical or algebraic expression.
