Answer:
1) 225
2) 2304
Step-by-step explanation:
1)
Use geometric mean of legs

2)
Use geometric mean of altitude

Substitute the value of y
6x-2(3x+12)=-12
6x-6x-24=-12
-24=-12
False
Final answer: No solution (the lines are parallel)
In bank A, after one year this would be the amount in the bank:
<span>$7,000 x 1.04 = $7280. </span>
<span>He has gained %280 interest. This means you'd need $1000 interest from bank B. </span>
<span>$13,000 would go into bank B... </span>
<span>If Seth's interest rate was 8.69% you could calculate the interest as: </span>
<span>(13000 x 1.0869) - 13,000 = $1129.70 which is a little much (but who'd complain). </span>
<span>This means the interest is lower than this, if it was 7.69% you could just substitute it into the same equation to find that he would get $999.70 interest. This isn't exactly $1000 but it is the most accurate answer to the nearest $100 :) He would then get $1279.70 interest altogether.. just 30 cents short</span>
