Answer:
Linear functions change at a constant rate per unit interval. An exponential function changes by a common ratio over equal intervals.
C.....hlj so yeah because it shows it on the diagram
Between 0 and 1 because it goes 0, 1/10, 2/10, and so on and so forth till 1
Suppose Alex has 3x stamps, Freddy has 5x stamps. After Freddy gives Alex 10 stamps, Alex has 3x+10 while Freddy has 5x-10
the new ratio is 7 to 9, so we have the equation: (3x+10)/(5x-10)=7/9
9(3x+10)=7(5x-10)
27x+90=35x-70
160=8x
x=20
So Alex has 3*20=60 stamps while Freddy has 5*20=100. Together they have 160
