You are part of a construction company that is supposed to build houses. An architect has left plans to build houses on each island. Bridges connect the islands. Island A and Island B have a total of 20 houses. Island A and Island C have a total of 13 houses. Island B and Island C have a total of 15 houses. A total of 24 houses is to be built on the three islands. Determine how many houses are to be built on each island. Explain how you arrived at your answer in detail.

Problem:

You are part of a construction company that is supposed to build houses. An architect has left plans to build houses on each island. Bridges connect the islands. Island A and Island B have a total of 20 houses. Island A and Island C have a total of 13 houses. Island B and Island C have a total of 15 houses. A total of 24 houses is to be built on the three islands. Determine how many houses are to be built on each island. Explain how you arrived at your answer in detail.

Facts:

A and Island B have a total of 20 houses

A and Island C have a total of 13 houses

B and Island C have a total of 15

There is a total of 24 houses

Explanation:

The 3 houses will have a total of 24, but A and  B have a total of 20 houses meaning that C is 4. However from the data: A and Island C have a total of 13 houses and B and Island C have a total of 15 we know B must be more because C will always have the same value meaning B is 2 more than A. With the knowledge of C being 4 because B and A are 20, B must be 11 and A Must be 9 as 11 is 2 more than 9 but they both still equal 20.

A is 9

B is 11

C is 4

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
