Answer:
234 hours
Step-by-step explanation:
To find the miles per hour, divide 72 by 2 and that equals 36. So 36 miles every hour. So then do 36 × 6 which equals 216. So this is 216 miles in 6 hours, but you still need 0.5 of an hour, so to find how far she travels in 0.5 of an hour, divide the amount she travels in one hour by two. So 36 ÷ 2 which equals 18. So she travels 18 miles every 0.5 of an hour. Then add 18 to the 216 which equals 234.

Given Equations
- 5x+3y=8--(1)
- 4x+7y=34--(2)
Let it has solution (x,y)
Add both


It will also have same solution (x,y)
Answer:
-1/4
Step-by-step explanation:
Take two points on the line
(-4,-1) and (0,-2)
Using the slope formula
m = (y2-y1)/(x2-x1)
= ( -2 - -1)/( 0 - -4)
= (-2+1)/ ( 0+4)
-1/4
The graph is missing, so i have attached it.
Answer:
From 0 hours to 2 hours.
Step-by-step explanation:
From the attached graph, we can see that on the y-axis, denotes the level of ibuprofen in the patient’s bloodstream while the x-axis denotes the amount of hours after the ibuprofen was taken.
Now, looking at the graph, we can see that the curve goes up from a time of 0 hours which corresponds to 0 mg of ibuprofen to a time of 2 hours which corresponds to 400 mg of ibuprofen.
After that point, the curve begins to to go down. Since we are concerned with increase, we will make do with the first statement.
Thus, we can say the period at which the level of ibuprofen increased was from 0 hours to 2 hours.
