Answer:

B. $f^{-1}(x)=\frac{x-4}{5}$

Step-by-step explanation:

To find the inverse of a function/equation:

Replace f(x) with y: y=5x+4
Switch x and y: x=5y+4
Solve for y: x-4=5y -> $y=\frac{x-4}{5}$
Write in standard inverse notation: $f^{-1}(x)=\frac{x-4}{5}$

I hope this helps!!

Hello I need help on the 4 questions please help thank you:D

boyakko [2]

Step-by-step explanation:

1. simple interest

I= p × r × t

I = 1050 × 4.5 × 2

I = $9450

2. principal

p = I/(rt)

p= 22.50/ (3× 3)

p = 22.50/9

p = $2.5

3. simple interest

I= p × r × t

I = 500 × 5 × 3

I = $7500

4. time

first convert r to decimal

r= r/100, r= 3.5 / 100

r= 0.035

t = i/(pr)

t = 43.75/ (2500× 0.035)

t = 43.75/ 87.5

t = 0.5 year or 6 months

Samaria has 6 more than three times as many pieces of candy as sydney. samaria has 36 pieces of candy. how many does sydney have

lesya [120]

For this case we have:

x: Number of candies that Sydney has

The equation to find the amount of Sydney sweets is given by:

$3x + 6 = 36$

We want to clear x:

$3x = 36-63x = 30$

$x = \frac{30}{3}$

$x = 10$

So, Sydney has 10 candies

Answer:

Sydney has 10 candies
