I start school tomorrow and just starting my work today, . I forgot a lot of it, but if any can help me with the slopes, graphs, equations, I'll truly appreciate it.
You need help on all that? Or just a portion? I think I might be able to help you on some of the problems.
14. x= 3 lol I used to be good at all the slope things and all that, but that was during like freshmen year and I forgot all of it.

1. Basically, that means that the line moves -3 across and 7 up, meaning that the gradient is -3/7, so -0.42 2. Moves -7 across, 0 up, so gradient = 0 3. Moves -1 across, 1 up, so gradient = -1 4. Moves 0 across, 10 up, so gradient = infinity (vertical line) 5. y=5x-13 6. y=2-x 7. y=-2x-3 8. 5x+3=-12 5x=-15 x=-3 9. (6x-8)-(5x+9)=3 6x-(5x+9)=11 6x-5x=2 x=2 10. 7x-8x+4=5x-2 4-x=5x-2 4=6x-2 6x=6 x=1 11. 3(x-2)=18 3x-6=18 3x=24 x=8 12. (3x+2)-2(x-4)=7 (3x+2)-(2x-8)=7 3x-(2x-8)=5 x=13 I'll do more later if you want

Geometry is the only math class that I liked in highschool....I never had a problem with plugging in numbers....
THis thread is pretty fun. I used to be good at all stuff but i'd forget it all right after I took the tests lol. Calculus sucks though, same with trig. I hope I can avoid all that kind of math in college.
13. (x+2)/3=8/15 (x+2)/3=0.53(3 is recurring) x+2=1.6 x=-0.4 14. 18/x=6 x=3 15. 5/7=10/y+2 5/7=10/14, therefore y+2=14 y=14-2 y=12 16. Area = 3.6cm x 4.2cm = 15.12cm2 Perimeter = 3.6cmx2 + 4.2cmx2 = 15.6cm 17. Area = 9mm x 9mm = 81mm2 Perim = 9+9+9+9 = 36cm 18. for the sake of typing, pi=# Area = #rsquared = 4x4# square inches = 16# square inches (totally accurate) = 50.2 square inches Circum = #d, d=2xr = 2x4 = 8 =8# square inches (totally accurate) =15.1 square inches 19. Area = #rsquared =81# =254.5 inches squared Circum = #d =18# =56.5 inches squared 20. Area = #rsquared root (36#/#)= radius root 36 = radius radius = 6 Circum = #d =12# =37.7 cm 21. 4x^5 y^2/2x^2 y = 2x^3 y 22. (5x^3 y^2)^2 = 25x^6 y^4 23. (6a^2-7ab-4b^2)-(2a^2-5ab+6b^2) = 4a^2-2ab-10b^2 24. x^3x^6=x^9 25. Triangle (right angled, scalene) 26. Regular Octagon 27. Parallelogram 28. Trapezium 29. Equilateral Triangle 30. Isosceles Triangle 31. x^2+3x=0 -b+-rootb^2-4ac all divided by 2a so, -3+- root(9-0) all over 2 (-3(+-)3)/2 = x x = 0 or x = -3 32. x^2-5x-24=0 (x-8)(x+3)=0 x=8 or x=-3 33. 3x^2+x-4=0 (3x+4)(x-1)=0 x=-1.3 (3 is recurring) or x=1 34. 3a + 6a^2 3a(1+2a) 35. 9b^2+12b+4 3b(3b+4)+4 36, 37, 38, you have to do this by yourself, as it is a graph (38 is a horizontal line on -3) 39. y=4x-3 40. y=-7/5x+5.8 41. y=1/6x+3 1/3 42. y=-4/3 x 43. (1) s+2t=6 (2) 3s-2t=2 (1)+(2) 4s=8 s=2 subs in (1) 2+2t=6 2t=4 t=2 check in (2) 6-4=2 44. (1) x-3y=3 (2) 2x+9y=11 (1)x3 3x-9y=9 (2) 2x+9y=11 (1)+(2) 5x=20 x=4 subs x=4 in (1) 4-3y=3 3y=1 y=1/3 check in (2) 8+3=11 45. SDP = 15x15 = 225 square inches RP = 64# = 201.1 square inches SDP's pizza is bigger. SDP = $9/225 square inches = $0.04 per square inch RP = $8.75/201 square inches = $0.044 per square inch SDP's pizza is the better buy 46. 1 gallon = 128 ounces therefore, 1 gallon = 128/8, eight oz glasses you can get 16 eight ounce glasses from 1 gallon, but there are 1.5 gallons, so you can get 1.5x16 glasses from the pitcher. 1.5x16 = 24 glasses. I deserve a merit (these stupid things given out at our school by teachers when you do something good)
Lol, what would Asian Zero do without you chingy? When I have math homework, I'm gunna make a thread, so you can do mine too.
Question: which grade and age are you in? Just curios because I want to compare it to when I did that sort of stuff in the different levels of school I've been through. Btw, damn I hate math. My worst subject of all in school. Looking at that stuff, I can't even remember how to solve some of it. And I'm not too far removed from school either (the last thing we did was derivasion and logarithms, and I had some real trouble with that stuff).

Damn, Swedish math must be somewhat retarded (although I'm not suprised). Some of that stuff we did your age, other at like age 17 or something.
