Option A: 
is the solution
Explanation:
The solution of the given inequality is the set of all the possible values of x.
The graph shows the number line in which the shaded region is from the right of -4 and the arrow of solution goes to infinity.
Also, There is a closed circle at the point -4.
This means that -4 is included in the solution set.
The solution to the inequality is the set of all the real values which are greater than or equal to -4.
Thus, the solution is x ≥ -4
Hence, the solution is

Answer:
7 quarters, 8 nickels
Step-by-step explanation:
So the system of equations you have is:
x + y = 15
0.25x + 0.05y = 2.15
Here's how to solve:
first, multiply both sides of the equation 0.25x + 0.05y = 2.15 by 100 to get rid of the decimal places:
25x + 5y = 215
Then, you can divide both sides by 5 to simplify it more:
5x + y = 43
Now, you have the system of equations:
5x + y = 43
x + y = 15
Now subtract the two equations:
4x = 28
divide both sides by 4
x = 7
plug x = 7 into the equation x + y = 15 to solve for y:
7 + y = 15
subtract 7 from both sides
y = 8
So you know that there are 7 quarters and 8 nickels.
