Answer:
yes
Step-by-step explanation:
youre trying to find when -1/4x + 3/2 = -x+ 3
so if you set it up like that and then solve for x you get 2
then, you know that 2 is your x value so just plug in x into one of the equations to get the y value
(i used -x+3 bc its easier)
-2+3=y
y= 1
so your solution is (2,1)

?
The answer is B) 23C above freezing.
0C is freezing temperature for water, that equals 32F
- We are to find the time (number of minutes) is would take for 23 mg of the substance to be remaining.
- The formula for time is written as:
t = [t1/2 x In(Nt/No)] / In 2
where:
t1/2 = Half life = 4 minutes
No = Initial quantity of the sample = 90 mg
Nt = Amount of the sample left = 23 mg
t = time elapsed = ?
Hence,
t = [4 x In (23/90)] / -In 2
t = 7.8731645610906 minutes
Approximately to the nearest hundredth = 7.87 minutes
Therefore, there will be 23mg of substance remaining after 7.87 minutes.
