amount increased to the toy = y
new price of the toy after adding markup = z
y= ( ( 25/100) × X )
therefore z= x+y
Julie's average speed which is the ratio of her distance covered to the time Taken to cover that distance ls <em>42.14 </em><em>miles</em><em> per hour</em>
Given the Parameters :
- Total miles traveled = 295 miles
- Total time taken = 7 hours
Recall :
- <em>Average speed = Distance covered / time taken </em>
Julie's Average speed = 295 / 7 = 42.14 mph
Therefore, Julie's average speed is 42.14 miles per hour.

Answer:
B) f(x) ≥ 3x + 4
g of x is less than or equal to negative one half times x minus 5
Step-by-step explanation:
From the above graph,
If point B is the solution of the system of inequalities, then point B must satisfies both inequalities
We can see from the graph that
Point B is located above (≥) the boundary line for f(x) and is also below (≤) the boundary line for g(x).
So we can say,
Point b satisfies the inequalities
Therefore,
The system is
f(x) ≥ (3x+4)
g(x) ≤ (-1/2x -5)
