Answer:
10
Step-by-step explanation:
If we plug in any negative number as x, the result will always be greater than 4, which rules out answers A and B
lets try plugging in 4 as x to test answer C:
2(8-4)
2(4)= 8
8 is greater than 4, therefore C is wrong.
Lets try 10 as X (answer D):
2(8-10)
2(-2)
-4
We know that -4 is less than 4, therefore it makes the inequality true! :)
Y = -6x + 2 . . . . . . . . (1)
-12x - 2y = -4 . . . . . . (2)
Putting (1) into (2), we have
-12x - 2(-6x + 2) = -4
-12x + 12x - 4 = -4
-4 = -4
Therefore, the system has infinite number of solutions.

Answer:
The inverse function is to calculate the number of rides; given the amount paid
Step-by-step explanation:
Given
per ride
Required
Explain the inverse function
First, we calculate the function
Let x represents the number of rides
So:
For the inverse function, we have:
Swap x and y
Make 3y the subject
Make y the subject
Replace y with the inverse function
The above is to calculate the number of rides; given the amount paid
