Ihave been trying to my 14 yr old for 4 hrs now:

2 function machines. input and output unknown but she needs to find the input (x) that makes the output of a 3 x output of b. here is the sum

i x5 -4 o
i x3 +8 o

i = input
o = output

£56

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
