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. x-value because its value is given






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






3. Shading goes down - or left






4. No fraction or decimal






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






6. Same slopes






7. Vertical line






8. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






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






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






11. mx+b=y






12. Shaded area






13. ROW x COLUMN






14. Hard - brackets






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






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






17. Dotted line






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






19. Soft - parentheses






20. Slope of 1/1 - through 0






21. Plug in vertices in objective function






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






23. Solid line






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






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






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






27. Solve using every equation (use linear combination)

28. 'Points' from BOTTOM to TOP






29. 1 -2 -3...maybe 0






30. 'Points' from side to side






31. No solution






32. A=a it is what it is






33. Function whose graph is a line






34. Intersecting points






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






36. Substitute AND simplify






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






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






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






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






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






42. A=b - then ac=bc






43. One or more solutions






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






45. e.g x






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






47. Put is simplest form






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






49. Opposite - reciprocal slopes






50. Horizontal line
