Answer:

We have to prove that,

-2(x+1)=8, then x= -5

L.H.S.

-2(x+1)=8

By distributive property,

-2x-2=8

Adding 2 both sides ( Additive property of equality )

-2x-2+2=8+2

-2x=10

Divide both sides by -2 ( Division property of equality ),

\frac{-2x}{-2}=\frac{10}{-2}

x=-5

= R. H. S

Hence, proved....

Step-by-step explanation:

distribute the -2 to (x+1) you end up with -2x-2=8 (multiplication property). Add 2 to both sides to get rid of the -2 of the left (addition property). 8+2=10. -2x=10 divide the -2 to both sides. x=-5 (division property).

Brut [27]

Answer:

n= 11.65 years

Step-by-step explanation:

Giving the following information:

Present Value (PV)= $33,000

Future Value (FV)= $15,000

Decrease rate (d)= 7%

<u>To calculate the number of years it will take to reach $15,000; we need to use the following formula:</u>

<u></u>

n= ln(FV/PV) / ln(1+d)  

n= ln(15,000/33,000) / ln(1.07)

n= 11.65 years
