Quiz - Solving Linear Inequalities

The inequality is solved correctly. Which of the following choices best describes the solution?

• All possible solutions are greater than or equal to -4

• All possible solutions are greater than 4

• All possible solutions are greater than or equal to 4

• All possible solutions are less than or equal to 4

Giovonni solved the inequality. Analyze his work to determine if he made a mistake. If no mistake was made then choose "no mistake". If a mistake was made, then decide which choice describes his mistake.

• No mistake

• He should have added 4x to both sides for his first step.

• He should have subtracted one from nine in his 2nd step.

• He should have flipped the inequality sign when dividing because the coefficient was negative.

• no solution

• -1

• 0

• 1

• 2
