(5,2)3.(-6.4)--3r + 17x+y=7Solve each system graphically.5. 2x + y = 141-)=-52. (3,7)2r + 5y = 286. x - y = -83x + y = 0Solve each system by substitution.13. y = 3x + 9- 2x + 1310. x + y = 6x + y = 414. x + 3y = 122x - 4y = 9Solve each system by elimination.15. 3x - 2y = 73x + 5y = -7Classify each system as independent consistent (IC), dependent consistent (DC), or inconsistent (I). Then statewhether the graphs are intersecting, coinciding, or parallel.9. x + y = 6x=y=4Solve each system algebraically.17. 5x - 2y = 7-2r + 3y = 616. x + 7y = 192x - 7y=-42x + 5y = -8-3x + y = 618. 2x - y = 3y = 2r + 87. 3x - y = -42x + y − 111. 2x + 2y = 8x + y = 419. 4x - y = −13x + 3y = -134.(-1,9)Write and solve a system of equations for each problem.21. Find two numbers whose sum is 3147 and whose difference is 135.x + 8y = 434x - 7y = 68. y = x + 1y>-4x - 212. 2x + y = 4x + 2y = 220. - 4x + 9y = 415x - 4y = -4422. Jay took 10 hr to travel a total of 1100 mi. He averaged 50 mi/hr in his car and 200 mi/hr in his smallplane. How much time did he spend in each?23. It takes Bryce and Caleb the same amount of time to row 6 mi upstream as it takes them to row 18 midownstream. If their rowing rate in still water is 4 mi/hr, what is the rate of the current?24. If it takes 5 hr for a plane to travel 1400 mi with the wind and 7 hr to make the return trip against thewind, find the wind speed and the plane's air speed.25. The difference between a two-digit number and five times the sum of its digits is 18. If the tens digit istwice the units digit, what is the number?26. The sum of the digits of a two-digit number is 11. If 45 is added to the number, the result is the numberwith its digits reversed. What is the original number?27. Evelyn invested $8400 in a CD and $9600 in a money market account whose APY is 1% less than that ofthe CD. If she made $804 in interest last year, what is the rate of interest on each account?28. Danielle has 87 nickels, dimes, and quarters whose total value is $10. If the number of nickels is sevenfewer than the total number of dimes and quarters, how many of each type of coin does she have?
