Front

What is the solution to the inequality -3 - 6(4x + 6) > -111?

Back

x < 3

Front

Which inequality is equivalent to 3x - y > 4?

Back

y < 3x - 4

Front

What does the graph of the inequality y ≤ -4 represent?

Back

It represents all points (x, y) where y is less than or equal to -4.

Front

Solve the inequality: 7(x + 3) < 5x + 13.

Back

x < -4

Front

What is the first step in solving the inequality 3x - y > 4?

Back

Isolate y to get y < 3x - 4.

Front

How do you graph the inequality y < 3x - 4?

Back

Graph the line y = 3x - 4 as a dashed line and shade below it.

Front

What does the inequality x ≤ -4 mean in terms of a number line?

Back

It includes all numbers to the left of -4, including -4 itself.

Front

What is the solution set for the inequality 5x + 2 < 17?

Back

x < 3.

Front

How do you check the solution of an inequality?

Back

Substitute a value from the solution set into the original inequality.

Front

What is the difference between a solid line and a dashed line in graphing inequalities?

Back

A solid line indicates 'greater than or equal to' or 'less than or equal to', while a dashed line indicates 'greater than' or 'less than'.
