Answer:
(D)y ≤ 3x − 1 y ≥ −x + 4
Step-by-step explanation:
The line f(x) is solid and goes through the points (0, 4) and (4, 0) and is shaded above the line.
The line that satisfies the point (0,4) and (4,0) is y=-x+4
Since it is shaded above the line, we have the inequality sign ≥.
Therefore, one of the lines is y≥-x+4
In the equation of the line y=3x-1
When x=0, y=3(0)-1=-1
When x=2, y=3(2)-1=5
Since it is shaded below the line, we have the inequality sign ≤ .
Therefore, the other line is y≤3x-1.
The correct option is D.
$ 25 was the cost of each ticket before applying the service fee.
<u>Step-by-step explanation:</u>
Given that the cost of two tickets including the service fee = $59
So, the cost of one ticket including the service fee =
Service fee on each ticket = 18%
Let the cost of 1 ticket without including the service fee = x
So, according to the data given in the question,
Hence, cost of each ticket before applying the service fee = $25
