Solve the problem using Gaussian elimination.The voltage across an electric resistor equals the current (in A) times the resistance (in ?). If a current of 
passes through each of two resistors, the sum of the voltages is 18. If 
passes through the first resistor and 
passes through the second resistor, the sum of the voltages is 66 V. Find the resistances.
A. resistance 1 = 7 ? and resistance 2 = 2 ?
B. resistance 1 = 7 ? and resistance 2 = 7 ?
C. resistance 1 = 2 ? and resistance 2 = 2 ?
D. resistance 1 = 2 ? and resistance 2 = 7 ?

The graph shows the numbers of performers who were elected to the Rock and Roll Hall of Fame from 1991 through 2008. Describe any trends in the data. From these trends, predict the number of performers elected in 2009.
A. The number of performers elected in last four years in the graph seems to be nearly steady except for the first few years therefore five performers will be elected in 2009. B. The number of performers elected in last four years in the graph seems to be nearly steady except for the first few years therefore seven performers will be elected in 2009. C. The number of performers elected in last four years in the graph seems to be nearly steady except for the first few years therefore eight performers will be elected in 2009. D. The number of performers elected in last four years in the graph seems to be nearly steady except for the first few years therefore six performers will be elected in 2009. E. The number of performers elected in last four years in the graph seems to be nearly steady except for the first few years therefore nine performers will be elected in 2009.
