Answer:

Infinitely many solutions

Step-by-step explanation:

-30 - 5b = b - 6(b + 5) ---- distribute -6 to both 'b' and '5'

-30 - 5b = b - 6b + 30 ------ combine like terms 'b' and '-6b' on the right side

-30 - 5b = -5b + 30 -------Add 30 to both sides to isolate 'x'

-5b = -5b --------- divide both sides by -5 to isolate 'x' even further

0=0 -----Infinitely many solutions

You can plug in any number for 'x' and get the same answer on both sides of the equation.

Use the compound interest formulas A=P1+

Bingel [31]

The accumulated value of an investment if the money is a. compounded semiannually; b. compounded quarterly; c. compounded monthly; d. compounded continuously is $30731.4 $ , $30785.98 $30823.14 , 30841.95

<h3>What is Interest ?</h3>

Interest is the amount received by a person as a result of investing certain amount of money for a certain period of time.

It is given that

Principal = $ 25000

Time = 3 years

Interest Rate = 7 %

The amount is given by

$\rm A = P( 1+ \dfrac{r}{n}) ^{nt}$

Compounded semiannually

n = 2

Compounded Quarterly

n = 4

Compounded Monthly

n =12

Compounded Continuously

P = P₀ $\rm e ^{rt}$

Therefore the accumulated value for

compounded Semiannually is

$\rm A = 25000( 1+ \dfrac{7}{200}) ^{2*3}$

A = $30731.4

Compounded Quarterly

$\rm A = 25000( 1+ \dfrac{7}{400}) ^{4*3}$

A = $30785.98

Compounded Monthly

$\rm A = 25000( 1+ \dfrac{7}{1200}) ^{12*3}$

A = $30823.14

Compounded Continuously

$\rm P = 25000 e ^{ 7 * 3 }$

P = $30841.95

Therefore the accumulated value of an investment if the money is

a. compounded semiannually; b. compounded quarterly; c. compounded monthly; d. compounded continuously is

$30731.4 $ , $30785.98 $30823.14 , 30841.95

What is f(x) - g(x)?

Gala2k [10]

$f(x)=9x^3+2x^2-5x+4\\\\g(x)=5x^3-7x+4\\\\f(x)-g(x)=(9x^3+2x^2-5x+4)-(5x^3-7x+4)\\\\=9x^3+2x^2-5x+4-5x^3+7x-4=9x^3-5x^3+2x^2-5x+7x+4-4\\\\=\boxed{4x^3+2x^2+2x}$
