SLO Test- Structures of Math 2

Front

What is the cost function for The Rug Store when installing carpet?

Back

Cost = 80 + 9.50x, where x is the number of square yards.

Front

What is the cost function for The Magic Carpet when installing carpet?

Back

Cost = 120 + 7.50x, where x is the number of square yards.

Front

Write an inequality to determine when The Rug Store charges more than The Magic Carpet.

Back

80 + 9.50x > 120 + 7.50x.

Front

What is the vertex of the parabola given by the equation y = 3(x + 5)² - 4?

Back

The vertex is (-5, -4).

Front

How do you determine if two rates are equivalent?

Back

Compare their unit rates; if they are the same, the rates are equivalent.

Front

What is the unit rate for 25 hours in 5 days?

Back

Unit rate = 25 hours / 5 days = 5 hours per day.

Front

What is the unit rate for 8 hours in 2 days?

Back

Unit rate = 8 hours / 2 days = 4 hours per day.

Front

What is the conclusion about the rates 25 hours in 5 days and 8 hours in 2 days?

Back

They are not equivalent because their unit rates are different.

Front

What does it mean if a graph has a minimum value?

Back

The graph reaches its lowest point at the vertex.

Front

What does it mean if a graph has a maximum value?

Back

The graph reaches its highest point at the vertex.
