Revolt · Accepted Answer

594 > -11n

Question 5

Which of these inequalities are equivalent to r > -11? Check all that apply.

Revolt · Accepted Answer

-r < 11; 3r > -33; -3r < 33

Question 6

Consider the inequality -20.2 > 0y. Which of the following must be true? Check all that apply.

Revolt · Accepted Answer

You cannot divide by zero.; The inequality is equivalent to -20.2 > 0, which is false.

Question 7

Question 7

Revolt · Accepted Answer

Both students are correct. When multiplying an inequality by a negative number like -7, the inequality symbol must be reversed. The two solutions, x > -14 and -14 < x, are equivalent because they both state that x is greater than -14, just written in a different order.

Question 8

Joseph received a $20 gift card for downloading music. Each downloaded song costs $1.29. Explain how to write and solve an inequality that can be used to determine the number of songs that he can purchase. Interpret the solution.

Revolt · Accepted Answer

To determine the number of songs Joseph can purchase, let x represent the number of downloads. Since each song costs $1.29 and he has a limit of $20, the inequality is 1.29x ≤ 20. To solve, divide both sides by 1.29, which gives x ≤ 15.503... Since he cannot buy a fraction of a song, he can download at most 15 songs.
