Answer:
A=-4 B=-8 C=8
Step-by-step explanation:
If you need to check these answers multiply the answer by the second number.
A) -4x-3=12 A negative times a negative is always positive.
B)-8x9=-72 A negative times a positive is a negative.
C) 8x-2=-16 A negative times a positive is a negative.
Answer:
the answer is confusing but you have to put it in as an equation and get and answer then you simplify that answer into a number sequence by rounding and estimating
Step-by-step explanation:
Answer:
The number of bacteria at initial = 187
Step-by-step explanation:
Given that the population of bacteria in a culture grows at a rate proportional to the number of bacteria present at time t.


Integrating both side we get
㏑ N = k t + C ------- (1)
Now given that after 3 hours it is observed that 500 bacteria are present and after 10 hours 5000 bacteria are present.
⇒ ㏑ 500 = 3 k + C -------- (2)
⇒ ㏑ 5000 = 10 k + C ------ (3)
⇒ ㏑ 5000 - ㏑ 500 = 7 k
⇒ ㏑
= 7 k
⇒ ㏑ 10 = 7 k
⇒ k = 0.329
Put this value of k in equation (2),
⇒ ㏑ 500 = 3 × 0.329 + C
⇒ C = 5.23
Put this value of C in equation 1 we get,
⇒ ㏑ N = k t + 5.23
Initially when t = 0 , then
⇒ ㏑ N = 5.23
⇒ N = 187
Thus the number of bacteria at initial = 187
Answer: x intercept is -3
y intercept is -9
Step-by-step explanation: 6(0) = 2y=-18, divide both sides by 2, get -9 as a y intercept
6x+2(0)=-18
divide both sides by 6, and get -3 as an x intercept
