Answer:
The graph shows that
As time increases, the amount of water in the pool also increases
It’s a positive number, it’s exactly the same distance from zero as the negative number he picked
120Rs is spend in 6 days on these things and distributive property is used
Properties of whole numbers are defined to operate basic arithmetic operations such as addition and multiplication, in an easy way. Applying these properties helps us to solve such math problems quickly, without even using calculators. These properties are almost similar to the properties of integers, although the definition for whole numbers and integers are different.
Total cost of a single day= 15 + 5 = 20Rs
∴ In 6 days total cost = 20 x 6 = 120Rs
Thus 120Rs is spend in 6 days on these things and distributive property is used.

The solution is at what point the two lines intersect.
Plug y into the other equation to get: 5x-4(5-3x)=-3
Multiply it out: 5x+12x-20=-3
Combine like terms and add 20 to both sides: 17x=17
Divide both sides by 17: x=1
Now plug the x value back into any equation to get the y value.
So you get y=5-3(1) --> y=2
The solution is (1, 2)
the point of intersection on the graph are (3,-2)
