Answer:
157286400 bacteria
Step-by-step explanation:
We are given the following in the question:
The bacteria increases 4 times every 6 hours.
Initially there are 150 bacteria.
Thus, we can write the function for number of bacteria after x hours,

We have to find the number of bacteria in 2.5 days.
1 day = 24 hours
Thus,

Putting x = 60 in the above equation, we get,

Thus, there will be 157286400 bacteria in two and a half days.
Answer:
Slope: 0.7 Y-Intercept: 9.8
Step-by-step explanation:
Answer:
2x+20+3x+10 = 180 (int. angles, parallel)
5x+30 = 180
5x=150
x=30
1) -3x-4y=10 ==> - 3x = 10+4y ===> 3x= -10-4y==> x=(-10-4y)/3
Now replace x by its value in 2)
2) -6x+y=-16 ==> - 6[( - 10- 4y)/3] + y = -16 ==> -2[(-10-4y] +y =- 16
+20+8y+y =- 16==> 9y = - 16 - 20 ==> 9y = -36 & y = - 4.
Now replace y by (- 4) in any of the 2 equations & you will find x = 2
X=8,3 . i have to type more to submit the answer
