The inverse function of 3x - 4 is (x+4)/3. so a

Step-by-step explanation:

f(x) = 3x - 4

y = 3x - 4 replace f(x) with y

x = 3y - 4 replace x with y and y with x.

3y = x + 4 solve for y

y = (x+4)/3 replace y with f-1(x)

f-1(x) = (x+4)/3

The first three terms of a sequence are given. Round to the nearest thousandth (if

tangare [24]

The 7th term of the sequence to the nearest thousandth is 223.949

<h3>What are geometric sequences?</h3>

These are sequence that increases in an exponential form.

The formula for calculating the nth term of a geometric sequence is expressed as:

Tn = ar^n-1

Given the following parameters

a = 75

r = 1.2

n = 7

Substitute the given parameter into the formula

T7 = 75(1.2)^6
T7 = 223.949

Hence the 7th term of the sequence to the nearest thousandth is 223.949

Josh earns $2700 each summer and puts the money in a savings account with a 4.5% simple interest rate. If he deposits the same a

iragen [17]

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Amount Josh earn each summer = $2700

Rate of simple interest = 4.5%

According to question, he deposits the same amount each year.

First summer, he deposited = $2700

In Second summer, he deposited = $2700×2= $5400

In Third summer, he deposited = $2700 × 3=$8100

At the end of his third summer, his money becomes,

$\text{Simple Interest}=\frac{P\times R\times T}{100}\\\\\text{Simple Interest}=\frac{8100\times 4.5\times 1}{100}\\\\\text{Simple Interest}=\$364.5$

As we know the formula for "Amount" that it becomes at the end of his third summer:

$Amount=P+S.I\\\\Amount=\$8100+\$364.5\\\\Amount=\$8464.5$

Hence, Option 'B' is correct.

WITCHER [35]

Answer:

-88x^3

Step-by-step explanation:

1) distribute the "2x"

(8x+8x-98x-2x-4x)x^2

a) add all like terms in parantheses

(-88x)x^2

b) multiply -88x and x^2

-88x*x^2=-88x^3

hope this helps!
