the images go in order to the graph
Okay, are you saying:
-a = 2, b = 2, c = 2, solve (a + b + c)
or
-2a * 2b * 2c(a + b + c)
I think it is mk because 4 plus 2 is sixty
Standard form of an exponential function is y=ab^x
when x=0, y=3, 3=ab^0, so you can figure out that a=3
when x=-1, y=6, 6=3b^(-1), b^(-1)=2, b=1/2
so the equation is y=3(1/2)^x
ratio is 3:5; 3 + 5 = 8
32/8 =4
so boys: 3*4 =12
girls: 5*4 = 20
boys to girls is 3:5 = 12:20
