Answer:
x = 1, y = 1
x = 2, y = 4
Step-by-step explanation:
substitution method:
x² = 3x - 2
x² - 3x + 2 = 0
(x - 2)(x - 1) = 0
x = 2
x = 1
Okay well the last number is in the thousandths place so put 216 over 1000. 216/1000. Now to simply. Find the biggest common denominator. the biggest common denominator is 8. So now you divide: 216÷8=27, 1000÷8=125 now put 27/ 125. ANSWER: 216/1000=27/125
Answer:
5.65 hours
Step-by-step explanation:
Given: Initial number of bacteria = 1000
N=1000(2)
To find: Time taken to: increase to 50,000
Solution: N=1000(2)
- 50,000=1000(2)
- Taking log,
- log 50,000 = log 1000(2)
- 4.7 = 3 + _ log 2
- _ = 1.7/log 2 = 5.65
Answer = 5.65 hours
_ = symbol after the two in the brackets that is high up and smaller.
