Front

How do you solve the equation 32 = -8a for the variable a?

Back

a = -4

Front

Translate the phrase: 'A number increased by 4 is no more than -18.'

Back

x + 4 ≤ -18

Front

What inequality does the number line graph represent if it includes all numbers greater than or equal to 3?

Back

x ≥ 3

Front

Match the graph with its inequality if the graph shows all values greater than or equal to 11.

Back

a ≥ 11

Front

What is the difference between an open dot and a closed dot on a number line?

Back

An open dot indicates that the number is not included (using < or >), while a closed dot indicates that the number is included (using ≤ or ≥).

Front

What is the solution set for the inequality x < 5?

Back

All real numbers less than 5.

Front

How do you graph the inequality x + 2 > 3?

Back

First, solve for x: x > 1, then graph with an open dot at 1 and shade to the right.

Front

What does the inequality x ≤ -2 represent on a number line?

Back

All real numbers less than or equal to -2, including -2 itself.

Front

How do you solve the inequality 3x - 5 < 4?

Back

Add 5 to both sides to get 3x < 9, then divide by 3 to find x < 3.
