Answer:
(a) 17/20 b.5/18/25 c. 1.255
<span>Multiply
the 1st equation by 5 and multiply the 2nd equation by 2. This will
eliminate the x's when you add the two new equations together.

<span>A) −2x+3y=8
B) 5x+4y=10
So we multiply A) by 5 and B) by 2
</span><span>A) −10x+15y=40
B) 10x+8y=20

Step-by-step explanation:
Answer:
$12000 at 5% for 8 years
Step-by-step explanation:
The amount in an account earning continuous interest is given by ...
A = Pe^(rt)
Then the interest earned is ...
I = P(e^(rt) -1)
For the two accounts, the interest earned is ...
I = 12000(e^(.05·8) -1) = 12000(0.491825) = 5901.90
I = 9000(e^(0.065·7) -1) = 9000(0.576173) = 5185.56
The $12000 account earns more interest, primarily because of the larger amount invested.
X Intercepts - (-7,0)
Y Intercepts - (0,9)
Hope this helps!
