Which system of equations represents the matrix shown below?
11 2 21 15
2 3 6 -29
13 9 2 | 22
11x +2y +212 - 15
A. 2x+3y +62--29
13x+9y+2z - 22
11x +2y - 212-15
B. 2xy +62--29
13x+9y+z=-22
11x +2y +212 = 15
C. 2x - y +z = -29
13x+9y + 4z =-22
11x + 2y - 212-15
D. 2x - 3y +z = -29
13x +9y+2z--22

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
