Answer:
The function is 
Step-by-step explanation:
From the question we are told that
The rate of growth is 
The total profit is 
$25,000
The time taken to make the profit is 
From the question
is the rate of growth
Now here x represent the time taken
Now the total profit is mathematically represented as
So using substitution method
We have that
So
![p(x) = {\frac{1}{2} [ e^{-u}} +c ]](https://tex.z-dn.net/?f=p%28x%29%20%3D%20%20%7B%5Cfrac%7B1%7D%7B2%7D%20%5B%20e%5E%7B-u%7D%7D%20%2Bc%20%5D)
recall and let 
At x = 2 years
$25,000
So
Since the profit rate is in million
$25,000 = 
$0.025 millon dollars
So
=> 
So the profit function becomes
Answer is D.Don't take out the square
Graph A because a graph of non proportional relationship will not pass through the origin (0,0) hope this helps! Remember to give me a like if it did please and thank you!
Nice use of brackets. We know exactly what you mean.
(10 - 7 + 2) / (-2 + 1) Notice that with an even number of - signs, you get a plus and with and odd number you get a minus.
(5) / (-1) = - 5 answer
Edit
Numerator
10 does not change.
+ - 7 Here a plus and a minus are put together. There is 1 minus sign which is an odd number of minus signs so the 7 is minus
- - 2 Here there are 2 minus signs. They become plus because 2 is even, and an even number of minuses become a plus so you have +2
10 - 7 + 2 = 5
Denominator
-2 does not change. It remains minus 2.
- - 1 There are 2 minus signs so this becomes plus 1.
- 2 + 1 = - 1
Numerator over denominator = 5/-1 = - 5. I'll probably run out of editing time. If you still don't understand, try and pinpoint the problem and we'll keep trying until you do see it. This question is worth it.
The solution (-4,2) satisfies for the system of linear equations 3x + 13y = 14; 6x + 11y = -2
<u>Step-by-step explanation:</u>
Step 1:
Given detail is the solution of the equations (-4, 2) ie, x= - 4 and y = 2
This implies that this solution should satisfy the given linear equations.
Step 2:
Substitute values of x and y in the equations and verify whether the right hand side equals the left hand side.
System 1 Eq(1) ⇒ LHS = 3(-4) + 13 (2) = -12 + 26 = 14 = RHS
System 1 Eq(2) ⇒ LHS = 6(-4) + 11(2) = -24 + 22 = -2 = RHS
Therefore, the first system of linear equations satisfy the condition.
