Find the solution for the variable y = -6 + y = -7

find the solution for the variable k =

k- 14 = -7

Y is equal to -1, and K is equal to 21

Step-by-step explanation:

1. add 6 to -7

2. y = -1

1. add 14 to 7

2. k = 21

y=-2x+50

Step-by-step explanation:

Let x be the number of weeks and y be the amount of waste. The linear equation may be expressed as,

                                        y = mx + b

where m and b are the slope and y - intercept, respectively. Substituting the corresponding values,

   (Week 5)                     40 = 5m + b

   (Week 10)                   30 = 10m + b

Solving for m and b gives the values as m = -2 and b =50. Thus, the equation is 

                                       y = -2x + 50
