Question

Determine whether the values -1 and 7.3 are solutions to the quadratic equation 3x^2 - 4x - 4 = 3

Answer 1

Determine whether the values -1 and 7/3 are solutions to the quadratic equation 3x^2 - 4x - 4 = 3

Answer 2

Use the table to answer the question.
When set off, a certain firework follows the path of the quadratic function h = -25/36x^2, where:
-- h = the height of the firework in feet.
-- x = the horizontal distance it travels in feet.
To determine how far the firework will travel before reaching the ground, determine which value of x in the table is a solution to the equation 0 = -25/36x^2 + 16 2/3x.
A. 12 feet
B. 36 feet
C. 48 feet
D. 24 feet

Answer 3

Ariel is trying to determine of x = -3 is a solution to the quadratic -3x^2 - 9x = 0. Which explanation demonstrates the correct reasoning?
A. Yes, x = -3 is a solution because substituting it back into the equation results in the following: x = -3, substituted -3(-3)^2 - 9(-3) = 0, evaluate 54 = 0, its a true statement.
B. No, x = -3 is not a solution because substituting it back into the equation results in the following: x = -3, substituted -3(-3)^2 - 9(-3) = 0, evaluate 54 not equal to 0, its a false statement
C. Yes, x = -3 is a solution because substituting it back into the equation results in the following: x = -3, substituted -3(-3)^2 - 9(-3) = 0, evaluate 0 = 0, its a true statement.
D. No, x = -3 is not a solution because substituting it back into the equation results in the following: x = -3, substituted -3(-3)^2 - 9(-3) = 0, evaluate 54 not equal to 0, its a false statement.
