X + 5y = 6
5y = -x + 6
y = -1/5x + 6/5....the slope here is -1/5. A perpendicular line will have a negative reciprocal slope. All that means is flip the original slope and change the sign. So we flip -1/5 and make is -5/1....and we change the sign...making it 5/1 or just 5. So our perpendicular line will have a slope of 5.
y = mx + b
slope(m) = 5
(2,-2)...x = 2 and y = -2
sub and find b, the y int
-2 = 5(2) + b
-2 = 10 + b
-2 - 10 = b
-12 = b
so ur perpendicular equation is : y = 5x - 12 <=

Answer:
8926 bacteria
Step-by-step explanation:
We have been given that the population of a bacteria in an experiment has been increasing by 80% each day. There were 25 bacteria at the beginning of the experiment. We are asked to find the number of bacteria in 10 days.
We will use exponential growth formula to solve our given problem.
, where,
y = Final amount
a = Initial amount,
r = Growth rate in decimal form,
x = Time.
Upon substituting our given values in above formula, we will get:
To find number of bacteria in 10 days, we will substitute in our formula as:
Therefore, there will be approximately 8926 bacteria in 10 days.
Answer:
The third one down
Step-by-step explanation:
The answer is -34
this is because you multiple both sides by -1 and that would make 34 negative and -j positive
