Example Questions

Example Question #1 : Setting Up Inequalities

If  and , where is  located

Possible Answers:

Quadrant I

The point will land on the x or y axis, therefore there is no quadrant for the scenario. 

Quadrant IV

Quadrant III

Quadrant II

Correct answer:

Quadrant IV

Explanation:

Because x is greater than zero, it will be to the right of the y axis. Because y is less than zero, it will be below the x axis. This is the fourth quadrant. 

Example Question #2 : Setting Up Inequalities

At a fair, there is a game where players step on a scale and weigh themselves. The objective of the game is for the host to guess the player's weight. A player loses if the host of the game can guess the player's weight within  pounds, inclusive. Suppose a player weighs  pounds. Write an inequality that represents the range of numbers such that the player loses. (Let  represent the guess weight.)

Possible Answers:

Correct answer:

Explanation:

For the player to lose, the host has to guess within  pounds of the player's weight, inclusive. Thus, the host can guess any number between  pounds  and  pounds ; that is, if  is the weight the host guesses, then , which translates to
