Joaquin is constructing the perpendicular bisector of ab. he opens his
compass so that the distance from the two points of the compass is wider
than half the length of ab. he then places the point of the compass on point
a and draws an arc across ab. what is his next step?

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
