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. Shading goes up - or right






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






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






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






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






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






7. Hard - brackets






8. Soft - parentheses






9. 1 -2 -3...maybe 0






10. A=b - then ac=bc






11. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3






12. 'Points' from side to side






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






14. No solution






15. [2x+3]=9 - [2x+3]=-9 write it both ways






16. Intersecting points






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






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






19. Shaded area






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






21. Plug in vertices in objective function






22. Shading goes down - or left






23. Set of ordered pairs (input and output)






24. Vertical line






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






26. e.g x






27. x-value because its value is given






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






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






30. Opposite - reciprocal slopes






31. Whats worth






32. Slope of 1/1 - through 0






33. Dotted line






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






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






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






37. One or more solutions






38. Solid line






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






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






41. Function whose graph is a line






42. A=b - then b=a






43. Same slopes






44. Horizontal line






45. Solve using every equation (use linear combination)

46. ROW x COLUMN






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






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






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






50. No fraction or decimal
