Algebra Formulas

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. Solid line






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






3. Plug in vertices in objective function






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






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






6. Opposite - reciprocal slopes






7. Soft - parentheses






8. One or more solutions






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






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






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






12. 'Points' from side to side






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






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






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






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






17. Horizontal line






18. Substitute AND simplify






19. Whats worth






20. Hard - brackets






21. A=a it is what it is






22. Shading goes up - or right






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






24. 'Points' from BOTTOM to TOP






25. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






26. A=b - then ac=bc






27. e.g x






28. Same slopes






29. x-value because its value is given






30. Set of all FIRST coordinates of the ordered pairs e.g. x (x -y)(input value - abscissa)






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






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






33. Solve using every equation (use linear combination)


34. Shading goes down - or left






35. No solution






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






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






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






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






40. Put is simplest form






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






42. Function whose graph is a line






43. mx+b=y






44. Function in mx+b=y form whose graph is a line






45. Intersecting points






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






47. 1 -2 -3...maybe 0






48. A=b - then b=a






49. Set of ordered pairs (input and output)






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