On a small island, 63 people live on 21 acres of land. If another 42 people move to the island how many acres will the 105 people live on?

Hey there!

If 63 people live on 21, acres, that means that 63/21 = 3, so every 1 acre is 3 people. So we can divide 105/3 and we get 35, which means 105 people will live on 35 acres.

Have a great day!

(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.
