I think that answer is B there is a association of greater growth occurring outside the lagoon because mainly the numbers each time get bigger like the first time it is 20 and then it is 31 so it goes up 11 more and then the third time it is 34 and it goes up 3 and then the last one sadly drops to 21.
The ratio would be 4 to 1
A function notation is expressed as f(x) = ax^b + cx^d + ..... where f(x) is equal to y, In this case, to r<span>ewrite 3x + 4y = 10 using function notation, we rearrange the statement and express in terms of x only. Hence
4y = 10 - 3x
y = (10 - 3x) /4 = f(x)
f(x) = 2.5 - 0.75x</span>
I believe it is A.
Option A is of two variables x & y and it is a straight line graph.
2x - 5 = y
