Substitute and simplify, X= 2, y = 9, z = -5
1. x + y + z = 6
2. 8x + 3 =
3. 4y + 3x2 =
4. xyz + 10 =
5. 2(y + 2) =

Which graph represents the equation y =4x

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
