Answer:
f(x) = y + (x*p)
Step-by-step explanation:
Since we are not given actual values we will need to make the function with only variables. Each variable will represent the following...
Fixed Cost: y
Cost per charm: p
Number of charms: x
Therefore, using the variables mentioned above we can combine them into the following linear function using the number of charms as our main input for our function...
f(x) = y + (x*p)
Answer:
b=9
x=5.5
Step-by-step explanation:
find the common ration
AB is 6, and XY is 3 (they are the corresponding sides)
ratio is 2 to 1 (6/3=2/1)
AC corresponds with YZ
XY is 4.5 so b is 4.5*2=9
ZY corresponds with CB
CB is 11, since XYZ is the smaller divide by 2 instead of multiplying by 2
