Classify each system of equations as having a single solution, no solution, or infinite solutions. y = 5 − 2x 4x + 2y = 10 x = 26 − 3y 2x + 6y = 22 5x + 4y = 6 10x − 2y = 7 x + 2y = 3 4x + 8y = 15 3x + 4y = 17 -6x = 10y − 39 x + 5y = 24 5x = 12 − y

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases

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
