Both −6 and 6 make the equation x22=18 true. Use set notation to express these solutions. When entering your response, list elements in the set from least to greatest, with a comma between each element in the set.
The solution to the inequality 4y+1>17 is y>4 . Use set notation to express the values of y that make the inequality 4y+1>17 true.
{y | y > 4}
Sophie, Adola, and Gilly are debating potential values in the solution set of the compound inequality −2≤2x−2<8 . Sophie says that −2 is a solution. Adola says that 5 is a solution. Gilly says that 2 is a solution. Which person is correct? Enter 1 for Sophie, 2 for Adola, or 3 for Gilly
The correct person is Sophie (1).
Which option correctly describes the values that make the inequality 2m<14 true when written in set notation? Option #1: {m:m<7} Option #2: {7:7<m} Option #3: {m<7:m} Option #4: {m<7} (1 point)
