Answer:
y = -2
Step-by-step explanation:
<u>SOLUTION :-</u>
Solve the equation.
- Add 8 to both sides in order to isolate the equation.
![=> y - 8 + 8 = -10 + 8](https://tex.z-dn.net/?f=%3D%3E%20y%20-%208%20%2B%208%20%3D%20-10%20%2B%208)
![=> y = -2](https://tex.z-dn.net/?f=%3D%3E%20y%20%3D%20-2)
∴ y = -2
<u>VERIFICATION :-</u>
To verify the solution of y , just put the solution (y = -2) in place of y in equation and check whether L.H.S = R.H.S.
L.H.S :-
-2 - 8 = <u>-10</u>
R.H.S. :-
<u>-10</u> (already given)
⇒L.H.S. = R.H.S. (verified)
Answer:
$2191.12
Step-by-step explanation:
We are asked to find the value of a bond after 10 years, if you invest $1000 in a savings bond that pays 4% interest, compounded semi-annually.
, where,
,
r = Rate of return in decimal form.
n = Number of periods.
Since interest is compounded semi-annually, so 'n' will be 2 times 10 that is 20.
![4\%=\frac{4}{100}=0.04](https://tex.z-dn.net/?f=4%5C%25%3D%5Cfrac%7B4%7D%7B100%7D%3D0.04)
![FV=\$1,000\times (1+0.04)^{20}](https://tex.z-dn.net/?f=FV%3D%5C%241%2C000%5Ctimes%20%281%2B0.04%29%5E%7B20%7D)
![FV=\$1,000\times (1.04)^{20}](https://tex.z-dn.net/?f=FV%3D%5C%241%2C000%5Ctimes%20%281.04%29%5E%7B20%7D)
![FV=\$1,000\times 2.1911231430334194](https://tex.z-dn.net/?f=FV%3D%5C%241%2C000%5Ctimes%202.1911231430334194)
![FV=\$2191.1231430334194](https://tex.z-dn.net/?f=FV%3D%5C%242191.1231430334194)
![FV\approx \$2191.12](https://tex.z-dn.net/?f=FV%5Capprox%20%5C%242191.12)
Therefore, the bond would be $2191.12 worth in 10 years.
The correct answer is y=2/3x+4 which is the last option :)
