Answer:x=-7

Step-by-step explanation:

Regroup terms.

8x-2=7x-98x−2=7x−9

2 Subtract 7x7x from both sides.

8x-2-7x=-98x−2−7x=−9

3 Simplify  8x-2-7x8x−2−7x  to  x-2x−2.

x-2=-9x−2=−9

4 Add 22 to both sides.

x=-9+2x=−9+2

5 Simplify  -9+2−9+2  to  -7−7.

x=-7x=−7

Answer:

x = - 7

Step-by-step explanation:

8x - 2 = -9 + 7x   (add 2 to both sides)

8x - 2 + 2 = -9 + 7x + 2

8x = 7x - 7           (subtract 7x from  both sides)

8x - 7x = 7x - 7 - 7x

x = - 7

If $2940 is invested at 3.2% compounded quarterly, how much is in the account after 8 years?
tino4ka555 [31]

Answer:

The future value is $3793.776

Step-by-step explanation:

Given

PV = 2940 --- present value

r = 3.2\% --- rate

t = 8 --- time

n = 4 --- quarterly

Required

Determine the future value

This is calculated using:

FV = PV(1 + \frac{r}{n})^{nt

So, we have:

FV =2940 * (1 + \frac{3.2\%}{4})^{4*8

FV =2940 * (1 + \frac{3.2}{400})^{32

FV =2940 * (1 + 0.008)^{32

FV =2940 * (1.008)^{32

FV =2940 * 1.2904

FV =3793.776
