Answer:
He needs to use 25.2 pounds to fertilize his lawn.
Step-by-step explanation:
In order to solve this problem we can use a rule of three in such a way that the content of the bag (36 pounds) can cover 10,000 ft² in the same proportion as "x" pounds can cover 7,000 ft², where "x" is the amount of fertilizer he needs to use.
36 pounds -> 10,000 ft²
x pounds -> 7,000 ft²
36/x = 10000/7000
10000*x = 36*7000
x = 36*7000/10000
x = 25.2 pounds
He needs to use 25.2 pounds to fertilize his lawn.
The correct answer would be 3. f(x) = -1, so you got to find the -1 in the y row of the table and just say that x =3 if y =-1.
