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. f(x -y)=x + y






2. Same slopes






3. Shading goes up - or right






4. Horizontal line






5. Intersecting points






6. A=b - b=c - then a=c






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






8. A=a it is what it is






9. 'Points' from side to side






10. One or more solutions






11. e.g x






12. Solve using every equation (use linear combination)


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






14. Set of ordered pairs (input and output)






15. Ax+By=C (letters are real - not zero)






16. 1 -2 -3...maybe 0






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






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






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






20. Vertical line






21. Hard - brackets






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






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






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






25. Set might require positive integers - natural #s - positive reals - etc.






26. Put is simplest form






27. Soft - parentheses






28. y-y{2}=m(x-x{2})






29. mx+b=y






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






31. Substitute AND simplify






32. Set of all SECOND coordinates of the ordered pairs e.g. y (x -y)(output value - ordinate)






33. Correct result - but doesn't work in equation






34. Whats worth






35. Function whose graph is a line






36. Slope of 1/1 - through 0






37. No solution






38. [2x+3]=9 - [2x+3]=-9 write it both ways






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






40. Opposite - reciprocal slopes






41. Dotted line






42. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






43. x-value because its value is given






44. No fraction or decimal






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






46. Shading goes down - or left






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






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






49. A=b - then ac=bc






50. Plug in vertices in objective function
