Multiplying the first equation and multiplying it by -8/3 (to get rid of the x), we get -8y/9+7y= -64+8=-56. Therefore, -56/(-8/9+7)=y and 8- 7(-56/(-8/9+7))=x by plugging it into the second equation
Answer:
The population after 8 years is 22752.
Step-by-step explanation:
Answer: 11
Step-by-step explanation:
Given
The equation of the line 
passes through the point 
So, point must satisfies the line i.e.
Therefore, the value of p is 11.
Answer:
-5 -√8 or ≈ -7.83
Step-by-step explanation:
<u>Solving the quadratic equation, to find its roots:</u>
- x^2 + 10x + 25 = 8 ⇒ The left side is perfect square
- (x+5)^2=8 ⇒ Getting square root of both sides
- x+5 = ± √8 ⇒ There are 2 roots
- x = - 5 ± √8
<u>The smallest root is:</u>
The formula for exponential growth is: Total = Starting value(1 + rate)^time
2018 to 2025 is 7 years:
Total = 50,000(1+0.037)^7
Total = 50,000(1.037)^7
Total = 64,479
