Answer 1

Answer: I hope it helps

1. F
2. D
3. H
4. I

Explanation:

`y \alpha x\\y= kx (1)\\Make=k-subject-of-the-formula\\(y)/(x) =(kx)/(x) \\\\\\`

`k = (y)/(x). \\when-y =3, x= 7 \\k = (3)/(7) \\Put - k- = 3/7 -in eq - 1\\y = 3/7x = F \\`

`(4n+3n^2+2)-(n-6n^2+1)\\4n +3n^2+2-n+6n^2-1\\\\3n^2+6n^2+4n-n+2-1\\9n^2+3n+1`

y = 2x-4

when x= 0

y = 2(0)-4

y =-4

y = 2x - 4

when x = 1

y = 2(1) -4

y = 2-4

y = 2

and so on....

A - Negative - the more slices eaten , the fewer there are

`f(x)= 2x^2 +x-12\\f(3) = 2(3)^2+3-12\\f(3) = 2*9+3-12\\f(3) = 18+3-12\\f (3) = 9`
