Explanation / Answer

1)3-0/0-10 = -3/10

2) dependent

3)x+y = 26000

x*6/100 + 3*y/100 = 1080

6x+3y = 108000

2x+y = 36000

so x = 10000

4)tanB = 105/139

B = 53 degrees

6)5+10/4+3 = 15/7

7)dy/dx = 14 - 0.4x

14 = 0.4x
x = 35 items

9)yes

10)domain = {7,8,9,10}
Range = {2}

11)10-0/0-7 = -10/7

12)-11

18)y = 2/5x - 11/10

19)(-3,0)

20)90-58 = 32
