Answer:
n = all real numbers
Step-by-step explanation:
7n+12=1/2(14n+24)
multiply each side by 2
2(7n+12)=2*1/2(14n+24)
distribute
14n+24 = 14n + 24
subtract 14n from each side
14n-14n+24 = 14n-14n + 24
24=24
this is always true
n = all real numbers

A quick way to answer all 1-10 is to multiply the starting price by 1.##. So for number 1 the equation would be 18 x 1.07 which equals $19.26. Question 2 would be

Answer:
∴35.97 mg caffeine would be left in the system after 5 hours.
Step-by-step explanation:
Given that,
A cup of coffee has approximately 310 mg of caffeine.
Caffeine decrease at a rate 35% per hour.
Exponential Function:

y(t)= Amount caffeine after t hours
= Initial amount of caffeine
r= rate of decrease
t = Time in hour.
Here y(t)=?,
= 310 mg, r=35%=0.35, t= 5 hours

=35.97 mg
∴35.97 mg caffeine would be left in the system after 5 hours.
