The inverse of f(x)=4x+5

Mathematics
1 answer:
frez [133]2 years ago
6 0

To find the inverse of a function switch the place of y (aka f(x) ) with x. Then solve for y.

Original equation:

y = 4x + 5

Switched:

x = 4y + 5

Solve for y by isolating it:

x - 5 = 4y + 5 - 5

x - 5 = 4y

(x - 5)/4 = 4y/4

\frac{1}{4}x-\frac{5}{4} = y

Hope this helped!

birute deposite $500 In a savings account with a simple interest rate of 1.3% . how could you use this information to find the i
vladimir2022 [97]

Money Birute deposited in a savings account = $500

Rate of simple interest per annum = 1.3%

▪︎We need to find the interest she will earn in 4 years.

We know that :

\tt \: \color{hotpink}simple \: interest \color{plum}=  \frac{principal \times rate \times time}{100}

In this case :

Principal = $500

Rate = 1.3%

Time = 4 years

Which means :

The simple interest she will earn in 4 years :

= \tt \frac{500 \times 1.3 \times 4}{100}

= \tt \frac{2600}{100}

\color{plum} = \tt\bold{\$26}

Thus, the simple interest she will earn in 4 years = $26

Amount = Principal + Interest

Amount she will gain after 4 years :

=\tt 500 + 26

\color{plum} = \tt\bold{\$526}

Thus, the amount she will gain after 4 years = $526

Amount change in her account = 526 - 500 = 26

We know that :

\tt \: \color{hotpink}percentage \: of \:  change\color{plum} =  \frac{change}{original \: price}  \times 100

Which means :

Percentage of change in her savings account :

=\tt  \frac{26}{500} \times 100

=\tt  \frac{26 \times 100}{500}

=  \tt\frac{2600}{500}

\color{plum} = \bold{\tt\bold{5.2\%}}

<h2>○=> Therefore :</h2>

▪︎Simple interest after 4 years = $26

▪︎Money she will earn after 4 years = $526

▪︎Percentage of change in her savings account = 5.2%

Wday is the area in square inches of the floor in the scale drawing
Mice21 [21]

Answer:

8

Step-by-step explanation:

Since 24 is the original length, you would have to see what number to divide by to get 6.

24 divided by 4 is 6.

Now we know that 1/4 is the scale factor, so apply that to 32.

32 divided by 4 is 6

That's your answer!

Brainliest would v much be appreciated
