Answer:
Only Katie is correct.
Step-by-step explanation:
Suppose the amount is $50.
Find the 40% by Tom's method:
50 / 100 = 0.5
0.5 * 4 = $2
- which is 4% of 50.
By Katie's method
50 / 5 = 10
10 * 2 = $20
- which is 40% of 50.
Answer:

By finding the roots of all the equations, we see that options A and D are the only ones that require an imaginary number in order to solve
Answer:
see explanation
Step-by-step explanation:
let y = f(x), then
y = 11x - 1
Interchange x and y and solve for y
x = 11y - 1 ( add 1 to both sides )
x + 1 = 11y ( divide both sides by 11 )
y = , hence
(x) =
2 because 1+1=2 and that’s why
