I = Prnwhere I is the interest, P is the principal, r is the decimal equivalent of the given rate, and n is the number of years. In this item, we assume that n is equal to 1. Solving for the interests, $200: I = ($200)(0.03)(1) = $6 $150: I = ($150)(0.03)(1) = $4.5The difference between the two calculated interests is $1.5.
Therefore, you could have earned $1.5 more if you invested $200 rather than $150.

- f-¹(x) = 69/5y
- f-¹(x) = 13 + 4y/(y + 10)
<h3>How to determine the inverse </h3>
The steps involved in determining the inverse of a function are;
- Replace f(x) with y in the equation describing the function
- Interchange x and y
- Solve for y
- Replace y by f-1(x)
If f(x) = 4/5x + 13
y = 4/5y + 13
y = 4 + 65 /5y
f^-1 = 4 + 65 /5y
f^-1(x)= 69/5y
If f(x)= 3/x+10 + 4
y = 3/y + 10 + 4
y = 3 + 4y + 10/(y + 10)
y = 13 + 4y/(y + 10)
f^-1(x) = 13 + 4y/(y + 10)
Thus, the inverse of the functions is 69/5y and 13 + 4y/(y + 10)

Answer: A
Step-by-step explanation: square has 4 sides 10/4=2.5
First get n's by them selves
-6 = 10n -4n (remember to always change sign when crossing the equals sign.
-6 = 6n ( subtract and take sign of the larger) ( then divide both sides by 6 to solve for n)
-1 = n
