# Algebra Formulas

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

**2. Shading goes up - or right**

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

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

**5. One or more solutions**

**6. Vertical line**

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

**8. Put is simplest form**

**9. Plug in vertices in objective function**

**10. 2 or more inequalities combined conjuction (both are true) -9<-4x-5<3**

**11. Relations have all points in common e.g same line**

**12. Shading goes down - or left**

**13. A=b - then ac=bc**

**14. Undoes operation a+(-a)=0**

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

**16. Solve using every equation (use linear combination)**

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

**18. A=b - b=c - then a=c**

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

**20. Correct result - but doesn't work in equation**

**21. Soft - parentheses**

**22. Whats worth**

**23. e.g x**

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

**25. Original status a+0=a - ax1=a**

**26. Opposite - reciprocal slopes**

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

**28. Slope of 1/1 - through 0**

**29. Substitute AND simplify**

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

**31. Dotted line**

**32. mx+b=y**

**33. Intersecting points**

**34. Shaded area**

**35. Function whose graph is a line**

**36. y-value - because its value depends on the x-value**

**37. Same slopes**

**38. 'Points' from BOTTOM to TOP**

**39. Set of ordered pairs (input and output)**

**40. 'Points' from side to side**

**41. No solution**

**42. Solid line**

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

**44. A=b - then b=a**

**45. f(x -y)=x + y**

**46. A=a it is what it is**

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

**48. ROW x COLUMN**

**49. Hard - brackets**

**50. x-value because its value is given**
