Figure ABCD is plotted on a coordinate plane. The figure transforms to create figure A'B'C'D'. Which transformation took place? A counterclockwise rotation through 90° about the origin B reflection across the origin C reflection across the y-axis D clockwise rotation through 180° about the origin E reflection across the x-axis

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
