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)
<span>b. 4+12÷2=4+6=10
c. (20–5)•3=15•3=45</span>
Think about it do you think it's subtraction or addition?
Answer: 13
Step-by-step explanation:
If you remember the quadratic equation formula;

You can easily extract what is under the root to find the discriminant.

a = 3
b = 7
c = 3

The difference between 11.0 and 12.5 is 1.5 and same with 12.5 and 14.0, so 1.5 is what the hair increases by every THREE months but if you want to find PER month, you are going to divide 1.5 by those 3 months to get .5 inches per month, so your slope will be 1/2
