What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols such as <, >, ≤, or ≥.

Front

How do you solve the inequality -8k - 4 ≤ -60?

Back

Add 4 to both sides: -8k ≤ -56. Then divide by -8 (remember to flip the inequality): k ≥ 7.

Front

What does the symbol '≥' mean in an inequality?

Back

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

Front

What is the first step to graph the inequality -6x - 4 > -40?

Back

Add 4 to both sides: -6x > -36, then divide by -6: x < 6.

Front

If Carol wants to buy vegetables and has $10.00 total, how do you represent the cost of vegetables?

Back

The cost can be represented as 3p + 5.5 ≤ 10, where p is the pounds of vegetables.

Front

What does the inequality 8x + 6 ≤ 42 represent in Cameron's bowling scenario?

Back

It represents the total cost of renting shoes and playing games, which must be less than or equal to $42.

Front

How do you interpret the inequality -2 < x?

Back

This means that x is any number greater than -2.

Front

What is the solution to the inequality 3p + 5.5 ≤ 10?

Back

Subtract 5.5 from both sides: 3p ≤ 4.5, then divide by 3: p ≤ 1.5.

Front

What does the graph of an inequality show?

Back

The graph visually represents all the possible solutions to the inequality.

Front

What is the difference between '>' and '≥'?

Back

'>' means greater than, while '≥' means greater than or equal to.
