The question is incomplete:
The fee for a parking permit consists of a one-time administration charge plus a monthly fee. A permit for 12 months costs $660. A 15-month permit costs $810.
What is the administration charge?
Answer:
$60
Step-by-step explanation:
To find the administration fee, first compute the difference between the two permits and divide by the three-month variation to identify the monthly fee:
$810-$660= 150
$150/3= $50
Next, multiply the monthly fee by 12 to determine the total monthly fee for 12 months, then subtract this from the 12-month permit cost to ascertain the one-time administration fee:
$50*12= $600
$660-$600= $60
This indicates that the administration fee is $60.
x= morning
y = afternoon
x + y = 10
x=10-y
5x + 6y =57
5(10-y) +6y =57
50-5y +6y =57
y=7
x=10-7 =3
verification: 3*5 = 15, 7*6 = 42, 42 + 15 = 57

Answer:
(1, -2)
Step-by-step explanation:
It’s important to note that the coordinates (1,3) and (1,-2) produce different outputs for the same x-axis value, indicating that this set does not fulfill the criteria for a function, but is rather a mere relation.
Recall that in a function, a single domain element cannot correspond to multiple outputs.
Thus, we can exclude (1,-2) to ensure it qualifies as a function.
