Flashcardziz Challenge #2 (Inequalities Review)

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is greater than, less than, or equal to the other.

Front

What does the symbol '≥' mean?

Back

The symbol '≥' means 'greater than or equal to'.

Front

What does the symbol '≤' mean?

Back

The symbol '≤' means 'less than or equal to'.

Front

How do you represent a situation where a tree grows over time?

Back

You can represent it with an equation like: initial height + growth rate * time.

Front

If a tree is 5.1 feet tall and grows at 2.5 feet per year, how do you express its height after 'y' years?

Back

The height after 'y' years is expressed as: 5.1 + 2.5y.

Front

What is the inequality for a tree that should not exceed 60 feet in height?

Back

The inequality is: 5.1 + 2.5y ≤ 60.

Front

How do you represent a plane descending at a rate of 100 feet per minute?

Back

You can represent it with an equation like: starting height - descent rate * time.

Front

If a plane starts at 10,000 feet and can fly no lower than 7,000 feet, what is the inequality?

Back

The inequality is: 10,000 - 100m ≥ 7,000.

Front

What is the cost structure for a taxi ride that charges a flat rate plus a per mile charge?

Back

The cost structure can be expressed as: flat rate + (per mile charge * number of miles).

Front

If a taxi charges $1.75 flat and $0.65 per mile, how do you express the total cost?

Back

The total cost can be expressed as: 1.75 + 0.65m.
