please help
Part A: Explain why x = 3 makes 4x − 1 ≤ 11 true but not 4x − 1 < 11. (5 points)
Part B: What value from the set {4, 5, 6, 7, 8} makes the equation 8x + 1 = 57 true? Show your work.

Best ResponseYou've already chosen the best response.0Part A : 4x  1 <= 11.....when x = 3 4x  1 < 11....when x = 3 4(3)  1 <= 11 4(3)  1 < 11 12  1 <= 11 12  1 < 11 11 = 11 (correct) 11 < 11 (false...because 11 is not less then 11) Part B : 8x + 1 = 57  subtract 1 from both sides 8x = 57  1 8x = 56  divide both sides by 8 x = 7.....any other value for x will not work
