Answer:
See method below.
Step-by-step explanation:
m/n + n/3 = 2
2/m + n = 4
First eliminate the fractions by multiplying the first equation by 3n:-
3m + n^2 = 6n...........(1)
and the second equation by m:-
2 + mn = 4m..............(2)
Now we solve using substitution:-
From equation (2):-
4m - mn = 2
m = 2 / (4 - n)
Now substitute for m in equation (1):-
6/ (4 - n) + n^2 = 6n
6 + n^2(4 - n) = 6n(4 - n)
6 + 4n^2 - n^3 = 24n - 6n^2
n^3 - 10n^2 + 24n - 6 = 0
This will not factor so we could solve this using graphical software.
To find the values of the variable m we substitute the found values of n into one of the original equations and solve for m.
The altitude is 6/4 but originally it’s 16 hope this helps ;)
Answer:
No, (-1,4) is not a solution.
Step-by-step explanation:
This is actually a simple problem...don't overcomplicate it!
All you need to do is plug the values into the equation and solve!
y < 2x + 5
4 < 2(-1) + 5
4 < 3
Answer: either b or c

Answer:
y = 5 * (3^x)
Step-by-step explanation:A scientist begins an experiment with a culture of 5 bacteria cells.
Every hour, the number of bacteria cells triples.
Which equation can be used to represent the number of bacteria cells, y, as it relates to time in hours, x?
:
I think it would be y = 5 * (3^x)
