(2x^2 - 5x + 3) - (-x2 + 4x - 5) a) x2 - x - 2 b) 3x2 - 9x - 2 c) 3x2 - x + 15 d) 3x2 - 9x + 8

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
