Answer:

24x^3−32x^2-34x+42

Step-by-step explanation:

Distribute 4x(6x^2+x-7) and -6(6x^2+x-7)

You get 24x^3-32x^2-34x+42-32x^2+42

Then simplify the answer by adding/subtracting each variable, since you can only simplify by like terms. And you get your answer

elixir [45]

Answer:

y = 5x + 8

Step-by-step explanation:

Start with y = mx + b: general slope-intercept form, equation of a line:

Replace m with 5, y with 8 and x with 0 (since the y-intercept is (0, 8):

8 = 5(0) + b. Then b must be 8, and the desired equation is

y = 5x + 8

A credit union client deposits $3,300 in an account earning 6.5% interest, compounded annually. What will the balance of the acc

astra-53 [7]

Answer:

The balance of account at the end of 36 years is $31,849.29

Step-by-step explanation:

We are given the following in the question:

P = $3,300

r = 6.5% = 0.065

t = 36 years

The compound interest is given by:

$A = p\bigg(1+\dfrac{r}{n}\bigg)^{nt}$

where A is the amount, p is the principal, r is the interest rate, t is the time in years and n is the nature of compound interest.

Since interest is compounded annualy we use n = 1

$A = 3300\bigg(1+\dfrac{0.065}{1}\bigg)^{36}\\\\A = \$31,849.29$

Thus, balance of account at the end of 36 years is $31,849.29
