Solve 2x2 - 9x - 5 = 0 by factoring.

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?

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

Find the maximum value of p= 4x + 5y subject to the following constraints :
