Find the Greatest Common Factor (GCF)
GCF = 14
Factor out the GCF (Write the GCF first, and then in parenthesis, just divide each term by the GCF)
14(140c/14 + 28/14 + -14a/14)
Simplify each term in parenthesis
<u>14(10c + 2 - a) </u>
6.4 micrograms were administered to the patient.
The general form of this equation would be:
, where A is the total amount left, p is the initial amount, r is the rate of decay, and t is the number of time periods.
For our question, A =0.1 since that is the amount left; p is unknown; r is -0.5, since it loses half of its mass; and t will be 6. 2 hours = 120 minutes/20 minutes = 6 20-minute increments:
Divide both sides by 0.5^6:
You first need to get the equation into y=mx+b form.
y= -3x-1
Now you can use the answer choices and figure out points.
The correct answer when you plug in (2,-7) is C.
-7= -3(2)-1
The answer to your question is 24 inches
Answer:
A. One line
Step-by-step explanation:
Let rearrange the system of equations into explicit forms:
The second equation is identical to the first one, which means that there is just one line.
