Total cost of 1 hour of parking is $2.
Explanation:
Given graph represents parking fees at a mall parking lot.
x-axis represents the hour of parking.
y-axis represents the cost of parking.
In the coordinate (1, 2),
1 represents hour of parking and 2 represents cost of parking
Hence, the coordinate (1, 2) represents the total cost of 1 hour of parking is $2.
The image of the graph is attached below.
Answer:

Step-by-step explanation:
Considering that the set has 24 cards on it, <em>numbered from 1 to 24 inclusive</em>, it means that the total number of cases is 24. Now, we have to find the number of favorable outcomes.
- Cases where the number is divisible by both 2 and 3:
In the interval 1 to 24 inclusive,
:
Numbers divisible by 2 => 2 4 6 8 10 12 14 16 18 20 22 24
Numbers divisible by both 2 and 3 => 6 12 18 24
Which means that there are <em>4-favorable outcomes for this scenario</em>.
- Cases where the number is divisible by 7:
In the interval 1 to 24 inclusive,
:
Numbers divisible by 7 => 7 14 21
Which means that there are <em>3-favorable outcomes for this scenario.</em>
- The total number of favorable outcomes is
. Since the total number of cases is
, the probability of favorable outcomes,
, is:

You need to have the rest of the problem. This is incomplete. ;-;
The given equations in this item are,
x² - y² =25
and
x + y = 25
It can be deduced that the first equation is a difference of two squares and can be factored out as that one shown below.
(x - y)(x + y) = 25
From the second equation, x+y = 25. Substituting this to the equation above,
(x-y)(25) = 25
Hence, x - y = 1
The system of linear equations is,
x + y = 25
x - y = 1
Adding the equations together,
2x = 26
x = 13
The value of y is 12.
Since both x and y are positive values then, this solution lies in the first quadrant.
ANSWER: (13,12)
