Andy and Samantha are performing an experiment in a science lab. The number of bacteria cells recorded by Andy in his experiment
is represented by the equation below, where B represents the number of bacteria, x hours after beginning the experiment.
B = 6x + 5
The number of bacteria cells recorded by Samantha in her experiment is represented by the equation below, where B represents the number of bacteria, x hours after beginning the experiment.
B = 2^x + 3
Using graphing technology, complete the statements.
After answer hours, the total number of bacteria cells for both experiments will be the same.
The total number of bacteria cells at that hour will be answer .

Answer:
numerator is 10
denominator is 25
Step-by-step explanation:
let x be the numerator
let y be the denominator
write 2 equations:
y = 5 + 2x
=
y is already isolated in the first equation, substitute into the second equation:
=
simplify:
=
cross multiply:
2x - 2 = 6(x - 7)
simplify:
2x - 2 = 6x - 42
subtract 2x:
-2 = 4x - 42
add 42:
4x = 40
divide by 4:
x = 10
plug in 10 for x in the first equation:
y = 5 + 2(10)
y = 5 + 20
y = 25
numerator is 10
denominator is 25
