Example Question #6 : Setting Up Inequalities
Set up the inequality expressed in the word problem below:
Elise went to the grocery store, and bought a bunch of sweet potatoes and onions. She knows she has less than 12 altogether. What is the inequality that expresses how many sweet potatoes (x) and onions (y) she could have bought?
is the correct answer, because the only thing the problem tells us is that the sweet potatoes and onions add up to a number less than 12. It does not say if one is more than the other, and does not say it could equal 12. Therefore the less than sign should not be underlined.
Example Question #2041 : Algebra Ii
If and , where is located
Quadrant IV
Quadrant I
Quadrant III
The point will land on the x or y axis, therefore there is no quadrant for the scenario.
Quadrant II
Quadrant IV
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.)
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 .
