# 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. A=a it is what it is

2. Soft - parentheses

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

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

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

6. 'Points' from side to side

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

8. Plug in vertices in objective function

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

10. Shading goes down - or left

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

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

13. A=b - then b=a

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

15. Same slopes

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

17. Shading goes up - or right

18. Whats worth

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

20. [2x+3]=9 - [2x+3]=-9 write it both ways

21. Opposite - reciprocal slopes

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

23. e.g x

24. Intersecting points

25. Dotted line

26. Solve using every equation (use linear combination)

27. ROW x COLUMN

28. One or more solutions

29. Hard - brackets

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

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

32. A=b - then ac=bc

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

34. Put is simplest form

35. mx+b=y

36. Horizontal line

37. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3

38. Substitute AND simplify

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

40. x-value because its value is given

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

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

43. Vertical line

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

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

47. Set of ordered pairs (input and output)

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

49. No fraction or decimal

50. 'Points' from BOTTOM to TOP
