Subjects : math, algebra
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. mx+b=y






2. e.g x






3. If IxI>5 then x>5 or x<-5






4. Put is simplest form






5. Solid line






6. Second step to linear combo. Fill in variable for whatever you solved for OR change equation to y= or x=






7. Original status a+0=a - ax1=a






8. Soft - parentheses






9. Solve using every equation (use linear combination)


10. Slope of 1/1 - through 0






11. Change of order a+b+c=a+c+b






12. Shading goes up - or right






13. A=b - then ac=bc






14. A=a it is what it is






15. f(x -y)=x + y






16. Rectangular array of #s written w/brackets (classified by # of numbers in row and column e.g. 3x3)






17. 'Points' from side to side






18. Change one equation with LCM (i think) and add up - cancelling one variable out






19. Shading goes down - or left






20. No solution






21. Change of grouping a+(b+c)=(a+b)+c






22. Relations have all points in common e.g same line






23. Same slopes






24. Vertical line






25. Undoes operation a+(-a)=0






26. Substitute AND simplify






27. Relations do not have all points in common e.g diff. lines that may intersect






28. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






29. y-value - because its value depends on the x-value






30. One or more solutions

39. Solve for (3x-4)(x+5)






40. Hard - brackets






41. Horizontal line






42. A relation in which each element of the domain is paired with one element in the range (no repeated x - however y can repeat)






43. Function whose graph is a line






44. Set of ordered pairs (input and output)






45. Plug in vertices in objective function






46. # set (2 -3) in x+1=y - 2+1=3
