Using a system of equations, it is found that the meter contains 20 dimes and 10 quarters.
<h3>System of equations:</h3>For the system, the variables are:
- x is the number of dimes.
- y is the number of quarters.
A dime is worth $0.1 and a quarter is worth $0.25. In total, the parking meter is filled with $4.50, hence:
There are twice as many dimes as quarters, hence:
Then:
There are 20 dimes and 10 quarters in the parking meter.

Answer:
D. y + 4 = 2x
Step-by-step explanation:
The graph has a y-intercept at (0, -4).
A. y=16 - 3x/4
if x = 0, y = 16. FALSE.
B. 24 + 3y = 6x
If x = 0, 24 + 3y = 0
3y = -24
y = -8. FALSE.
C. 4y + x = 16
If x = 0, 4y = 16
y = 4. FALSE.
D. y + 4 = 2x
If x = 0, y + 4 = 0
y = -4. TRUE.
y = 4 + 2x has the same y-intercept as the graphed line.
