<span> 1.5(0.8x-1.2) = 0.2x+1.2
1.2x-1.8=0.2x+1.2
+1.8 +1.8
1.2x=0.2x+3
</span>
1.2x=0.2x+3
-0.2x -0.2x
x=3
Answer: A. y=x²-9x+20
Step-by-step explanation:
As we can see from the graph there are two x-intercepts: (4,0) (5,0)
The easiest way we can do, is we plug these two values into each of the choices.
A. y=x²-9x+20
(4, 0) YES
(5,0) YES
B. y=x²-8x+18
(4, 0) NO
(5, 0) NO
C. y=x²+9x+20
(4, 0) NO
(5, 0) NO
D. y=x²+x-12
(4, 0) NO
(5, 0) NO
Therefore, the answer should be y=x²-9x+20
Hope this helps!! :)
Please let me know if you have any questions
The answer is 87,455
P(x) = P(0) * nˣ
P(x) - the final population after period x
P(0) - the initial population
n - the growth factor in decimal
x - period of time
x = 3 hours
P(3) = 25,143
P(0) = ?
n = 100- 34% = 66% = 0.66
P(x) = P(0) * nˣ
25,143 = P(0) * 0.66³
25,143 = P(0) * 0.287496
P(0) = 25,143 / 0.287496
P(0) ≈ 87,455
