Trey, Amelia, and Cho are discussing the solution set to the equation x2+9=45 . Trey says the solution is {6} . Amelia says the solution is {−6,6} . Cho says the solution is {−6} . Which person has found the correct solution set? (1 point) Responses Cho Cho None of them are correct. None of them are correct. Trey Trey Amelia Amelia
Amelia has found the correct solution set. The solutions to the equation x^2 + 9 = 45 are x = -6 and x = 6.
The values −1 and 1 make the equation 3x2+7=10 true. Use set notation to express the solution to the equation.(1 point) Responses (x=−1,x=1) left parenthesis x equals negative 1 comma x equals 1 right parenthesis (−1,1) left parenthesis negative 1 comma 1 right parenthesis {x=−1,x=1} left brace x equals negative 1 comma x equals 1 right brace {−1,1}
{ x = -1, x = 1 }
The solution set of the inequality 3(b−4)+2b>3 is the set of values of b greater than three. Which set notation correctly expresses the solutions?(1 point) Responses {b:b>15} left brace b colon b greater than 15 right brace {b:b<15} left brace b colon b less than 15 right brace {b:b<3} left brace b colon b less than 3 right brace {b:b>3}
{ b : b > 3 }
