7 0

Step-by-step explanation:

5×0.3+2y=20

5×0.3= 1.5

1.5+2y=20

Answer:

y= 9.25

Step-by-step explanation:

5x + 2y = 20

2y = 20 - 5(0.3)

2y = 20 - 1.5

y = 20/2 - 1.5/2

y = 10 - 0.75

y = 9.25

The domain of a function are its possible input values

The domain of the function is (b) all real numbers greater than or equal to 0.

From the graph, we have the following observations

The above observations imply that; the domain starts from 0

Hence, the domain of the function is the set of all real numbers greater than or equal to 0.
