Answer:
<h2>39 minutes</h2>
Step-by-step explanation:
In this problem we can see that there is a constant/flat rate charge of $4 on every first minute
we can model the cost for calls as

where x is the number of extra minutes spent
given that y = $13.75
We can simply substitute our given values into the equation 1 above and solve for x

Divide both sides by 0.25 to find x
<h3>Answer: C) 180 or 0</h3>
====================================
Work Shown:
Let y = sin(x). Solve for y then solve for x
-4+6*sin(x) = -4+4*sin(x)
-4+6*y = -4+4*y ... replace sin(x) with y
6y-4y = -4+4
2y = 0
y = 0/2
y = 0
sin(x) = 0 ... plug in y = sin(x)
x = arcsin(0) or x = 180-arcsin(0)
x = 0 or x = 180
We have two solutions here since
sin(0) = 0 and sin(180) = 0
The solutions x = 0 and x = 180 fit in the interval 
Answer:
x>6 = x is greater than 6
x>6 = 6 is less than x
x>6 = x is to the right of 6 on a number line (Vertical above x)
x>6 = 6 is to the left of x on a number line (Vertical below x)
x>6 = What else is there? If you guys can find anymore, answer in the comments.
