Plzz helpp Find the inverse function

Mathematics

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

f(x) =  {x}^{2}  + 5

y =  {x}^{2}  + 5

{x}^{2}  + 5 = y

Subtract sides 5

{x}^{2}  + 5 - 5 = y - 5

{x}^{2}  = y - 5

x = ± \sqrt{y - 5}

x≠ - \sqrt{y - 5}

Because x is a positive number but -√y-5 is a negative number thus it's unacceptable.

So ;

x =  \sqrt{y - 5}

_________________________________

{f}^{ - 1}(x)  =  \sqrt{x - 5}

Done...

You want to get the measure of y.

4x - 2y = 10
-4x -4x
------------------
-2y = 4x + 10
----- ---- ----
-2 -2 -2
y = -2/1x + -5

You earn $28 for washing 7 cars. How much do you earn for washing 6 cars?
iren [92.7K]

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━  

Since you can earn 28 dollars by washing 7 cars, and you want to find the amount money you can make by washing 6 cars.

\frac{28}{7} = \frac{x}{6}

First, you should find the amount of money you can make by washing 1 car (unit rate).

\frac{28}{7} = \frac{x}{1}

To get from 7 to 1, you have to divide 7 by 7; 7 ÷ 7 = 1.

Do the same thing to the numerator; 28 ÷ 7 = 4.

Now you know how much you make by washing 1 car, you need to find how much you make by washing 6 cars.

\frac{4}{1} = \frac{x}{6}

To get from 1 to 6, you multiply by 6. 1 times 6 equals 6.

Now do the same thing to the numerator; 4 × 6 = 24.

You can earn 24 dollars by washing 6 cars.
