Answer:
f^-1(x) = 3 - 5x, second option
Step-by-step explanation:
To determine the inverse simply interchange the variables and solve for y;
f(x) = 3 - x / 5 -> Interchange the variables
x = 3 - y/5 -> Multiply either side by 5
5x = 3 - y -> Subtract three from either side
- y = 5x - 3 -> Divide either side by - 1
y = - 5x + 3
Your solution is f^-1(x) = 3 - 5x
16,500
60 minutes in an hour / 12 minutes = 5
5 * 3,300 = 16,500
Answer:Thus, a product that normally costs $20 with a 40 percent discount will cost you $12.00, and you saved $8.00. You can also calculate how much you save by simply moving the period in 40.00 percent two spaces to the left, and then multiply the result by $20 as follows: $20 x . 40 = $8.00 savings.
Step-by-step explanation:
Equation of circle at center (h,k) is given by
Given that center is at (5,0) that means h=5 and k=0
plug both values into above formula
...(i)
Given that circle passes through point (1,1) so it will satisfy above equation
Now plug this value of r^2 into equation (i)
which best matches with choice C
Hence is the final answer.
