You deposit $6,700 in a money-market account that pays an annual interest rate of 3.3%. The interest is compounded quarterly. How much money will you have after 4 years?

Answers

3.3% per year is 0.825% per quarter, and 4 years is 16 quarters, so your result will be $6,700 x (1.00825)16 = $7,641.29, a total return of just over 14%.

Can someone please help me with these ?

Answer:

Step-by-step explanation:

11) $√(8x+33) =3\n8x+33=9\n8x=-24\nx=-3$

Subtract 4 from both sides. Square each side. Subtract 33 from both sides. Divide each side by 8. Your answer is -3.

12) $7x-17=x^2-2x+1\n0=x^2-9x+18\n0=(x-6)(x-3)\nx=6, x=3$

Square both sides. Put all numbers on one side of the equation so that you can be equal to zero. Factor out and solve for x.

What is the solution to 1/3x-5+171=x

Answers

(1/3)x-5+171=x
I move the x on the right to the left so
(1/3)x-x-5+171=0
I then simplify so
(-2/3)x+166=0
I subtract 166 from both sides so
(-2/3)x = -166
Then I divide (-2/3) from both sides so
x = -166/(-2/3)
x = 249
and that's the answer
hope this helps

x in (-oo:+oo)

(1/3)*x-5+171 = x // - x

(1/3)*x-x-5+171 = 0

166-2/3*x = 0 // - 166

-2/3*x = -166 // : -2/3

x = -166/(-2/3)

x = 249

x = 249
