1.(09.01) Line R is represented by the following equation: x + y = 2 Which equation completes the system that is satisfied by the solution (1, 1)? (4 points) 2x + y = 2
4x - 2y = 2
2x - 2y = 2
x + y = 4

Which is the equation of a line perpendicular to the line with the equation 3x+4y=8

Can someone me out here and the tell me the greatest common factor

Someone answer asap for ! 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
