For the function with the greatest rate of change, what is its value when x = 10? Options: 13, 17, 25, 28

28

Front

The set of ordered pairs represents a relation. {(0, 2), (1, 3), (1, 4), (2, 5), (3, 5)}
Which statement about the relation is true?

Back

The relation is not a function, but removing (1, 4) and replacing it with (4, 1) would make the new relation a function.

Front

A linear function of x is graphed on a coordinate grid. The points (6, 34) and (18, 26) lie on the graph of the function. What are the rate of change of the function and the value of the function when x = 24?

The graph shown represents the rate at which water drains from a tank once the drain is opened.
Which statement correctly describes the graph? Options: The water is draining at a constant rate of 1/2 gallon per minute, and the tank contained exactly 14 gallons when the drain was opened. The water is draining at a constant rate of 2 gallons per minute, and the tank contained exactly 14 gallons when the drain was opened. The water is draining at a constant rate of 5 gallons per minute, and the tank contained exactly 14 gallons when the drain was opened. The water is draining at a constant rate of 14 gallons per minute, and the tank contained exactly 1/2 gallon when the drain was opened.

Back

The water is draining at a constant rate of 1/2 gallon per minute, and the tank contained exactly 14 gallons when the drain was opened.

Transformation: reflection across the y-axis; Relationship: similar and congruent

Front

Sequence of transformations to show congruence between triangle RST and triangle R¹S¹T¹:
- a translation 3 units up and then a translation 5 units to the right
- a translation 2 units to the right and then a reflection across the y-axis
- a reflection across the y-axis and then a translation 1 unit to the right and 3 units up
- a translation 1 unit to the right and 3 units up and then a reflection across the y-axis

Back
