The answer is 1/2. if you do 15/124 x 230/30 it equals 115/124. then divide that by 230/124 with give you 1/2
Answer:
parallel means that the line has the same slope as
Slope point formula :
y - y1 = m (x - x1)
m represents the slope.
x and y represents the point in the form (x, y).
Since the slopes are the same we can substitute the slope into the formula:
then we can substitute our point (2, - 5)
Final answer:
Change the - 5 to positive.
Leave y by it's own and subtract 5 to get rid of it. Do this both sides to make it equal.
Get rid of the brackets by multiplying:
simplify:

Answer:
Step-by-step explanation:
- Initial amount of drug = 50 mg
- Remains after each hour = 85%
- Time = t
<u>This relationship can be shown as a function:</u>
<u>After 4 hours remaining drug in blood:</u>
- y(4) = 50(0.85)^4 = 50(0.522) = 26.10 mg
In order to write this equation, you must first graph the points. The x-intercept of -2 means the point on the graph is at (-2,0). The y-intercept of -1 means the point on the graph is at (0,-1). To get our slope, we must first subtract the x-intercept from the y-intercept.
(-2,0)
-(0,-1)
=(-2,-1)
Rise (y) over Run (x)
Our slope would be 1/2.
Now that we have our slope, let's get our equation set up. y = mx + b
y = 1/2x + b
Now we plug in one of our coordinates to get our "b".
-1 = 1/2(0) + b
-1=b
Now our line equation is y = 1/2x - 1
Hope this helped!

The answer is 1038 because if you minus 720 and 360 you get 360 then add 720 and 360 and you get 1038
