Help and give an explanation, please! Nancy wrote two equivalent expressions, if she sets them equal will it have one solution, no solutions, or infinitely many solutions? Explain your reasoning.

Which representation has a constant of variation of -2.5

What is the x-intercept and y-intercept of the equation 2x+1. 2o

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
