11111nata11111 [884]

Answer:

22.459 pounds of wood

Step-by-step explanation:

Total amount of wood in store = amount of pine wood purchased + amount of cedar in the store

Total amount of wood in store = 13.145 pine wood + 16.903 cedar wood

Total amount of wood in store = 30.048 pounds of wood

If acme lumber had sold 7.589 pounds of lumber after 6 months, the amount of pounds of woods that the company have left to sell = Total amount in store initially - amount sold after 6 months

Amount of pounds of woods that the company have left to sell  = 30.048 - 7.589

The amount of pounds of woods that the company have left to sell  = 22.459 pounds of wood

(3,-2);slope 1/3 what is the answer?
wolverine [178]

Answer:

y = \frac{1}{3} x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = \frac{1}{3} , then

y = \frac{1}{3} x + c ← is the partial equation

To find c substitute (3, - 2) into the partial equation

- 2 = 1 + c ⇒ c = - 2 - 1 = - 3

y = \frac{1}{3} x - 3 ← equation of line
