Given:
To find:
The values of f(2) and f(5).
Solution:
If an ordered pair 
is in the function 
, then 
.
In the given set of ordered pairs one ordered pair is (2,3). So, by using the above definition, we get
In the given set of ordered pairs one ordered pair is (5,6). So, by using the above definition, we get
Therefore, the value of f(2) is 3 and the value of f(5) is 6.
The answer is B. The shape is staying the exact same, it’s just moving.
Answer:
Adult Ticket Price = $13
Child Ticket Price = $13
Step-by-step explanation:
Let price of adult ticket be "a" and child ticket be "c"
13 adult and 14 child equals $351, so we can write:
13a + 14c = 351
and
2 adult and 7 child equals $117, thus we can write:
2a + 7c = 117
We multiply 2nd equation by (-2) to get:
-2 * [2a + 7c = 117]
= -4a -14c = -234
Adding botht he "bold" equations, we get:
13a + 14c = 351
-4a -14c = -234
------------------------
9a = 117
a = 117/9 = 13
Now to find b, we use the value of a gotten in the first equation:
13a + 14c = 351
13(13) + 14c = 351
169 + 14c = 351
14c = 182
c = 182/14 = 13
Hence,
<em>Adult Ticket Price = $13</em>
<em>Child Ticket Price = $13</em>
For this case, the first thing you should do is multiply the rate of decrease by time.
We have then:
(3.6 × 10-2) * (1.8 × 104)
= 648 mm
We are going to convert this number into scientific notation:
= 6.48 * 10 ^ 2 mm
Rounding we have:
= 6.5 * 10 ^ 2 mm
Answer:
The water level in the tank decreases in 6.5 * 10 ^ 2 millimeters in 5 hours
5x + 4 < 29
5x < 29 - 4
5x < 25
x < 25/5
x < 5
solution set is { 3,4 }
