Answer:
You will need about 13 tables.
Step-by-step explanation:
I divided the number of guests by 12 and got 12.5 however you can't have half of a table so I rounded up and got 13.
The inverse function is f(x) = 
You can find the inverse of any function by switching the f(x) value and the x value. Then solve for the new f(x) value. The result will be your inverse function. Below is the step-by-step process for solving this one.
f(x) = 2x + 1 ---> Switch the f(x) and x values
x = 2f(x) + 1 ---> Subtract 1 from both sides
x - 1 = 2f(x) ----> Divide each side by 2.
= f(x) ---> Switch the order so that it looks like a function.
f(x) = 
And that would be your inverse function.
Answer: 0.1
Step-by-step explanation:
You do 25×.52= 13 then you add 13 to 25, so its 38.
or 25×1.52= 38
For A, the scares depend on the hours studying, there is a positive relationship between the two.
