The equation is not setup properly, possibly it is your teacher's fault.
From external research, I would say the answer is x = -12.
Answer:
Step-by-step explanation:
Given
-- initial
Required
The exponential equation
The exponential equation is
Where
We used minus, because the rate decreases..
So, we have:
So:
Hence:
<span>Leah, Let x=Blair's fish and 2x= Jay's fish; yet together they caught 27 fish. So, x + 2x=27; Combine the like terms. So, 3x=27; Now divide both sides of the equation by 3, therefore, x=9 which is the amt of fish Blair caught. So, 2(9)=18 is the amt of fish Jay caught. Check: 9 +2(9)=27; 27=27.</span>
The plus sign means that we have to sum all the terms inside of the second parenthesis, while the minus sign means that we have to change all the signs inside the last parenthesis:
Now we only have to gather all like terms:
