a. 5712.04

b. 5712.04

c. 79.97

d. 878.71

e. 12.30

f. 67.67

Step-by-step explanation:

B- 17136.12 /30= 5712.04  

C- 5712.0r x 0.014 =79.97  

D- 712.04 x 29= 20,649.16  

   5723.04 x 1 = 5712.04  

                         = 26,361.20/ 30  

                               =878.71  

E- 878.71(0.014)= 12.30  

F- 79.97 -12.30 = 67.67

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
