Hello!
The equation representing the statement is the third one, x=4(x-15). In fact, Juan’s age is x, his age 15 years ago is (x-15) and it is said that his age now is 4 times his age 15 years ago, so x=4(x-15).
If my answer is not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistakes.
Answer:
Assets: Liabilities: Net Worth:
100,000 18,000 $211,500(Assets) - $24450(Liabilities)
47,000 4,500
25,000 1,500 Net Worth = $187,050
22,000 450
15,000
2,500
Step-by-step explanation:
First, list your assets (what you own), estimate the value and add up the total, examples include: money in your bank account, your car, personal property (jewelry, furniture etc.)
Then, list your liabilities (what you owe) and add up the outstanding balances, examples include: mortgage, student loan, etc.
Finally, subtract your liabilities from your assets to determine your personal net worth.
It has at least one or two solutions it depends on how you write it down
Try this option:
1. if 8*x²+b*x+3=8*x²+p*x+q*x+3, then ⇒ b=p+q.
2. p*q = max_value (b²/2), if p=q=0.5*b, and p*q→-oo, if p>0 and q<0 or p>0 q<0.
3. example:
given 8x²+10x+3, the student rewrites it as a) 8x²+5x+5x+3 (5*5=25-max value); b) 8x²+0.01x+9.99x+3 (9.99*0.01=0.0999→0); c) 8x²-20x+30x+3 (p*q=-600).
answer: (-oo;0.5b²)
