Answer:
Exponential Function
Step-by-step explanation:
y values increase by x4
Answer:

Step-by-step explanation:
We are finding the equation of the line that coincide with line segment AB.
So, we can find the equation by using points A and B.

Slope of line (m) = 
Since slope = 0, therefore the line is parallel to x-axis.
The equation of line is given by 
where
is slope and
is y-intercept.
So equation of line AB:
where
and 



Answer:
Our maximum is 19 when x=3 and y=7 and our minimum is -21 when x=3 and y = -3
Step-by-step explanation:
First, we can graph these inequalities out. As you can see in the picture, the three vertices where the inequalities all connect form a triangle. We can check each of these vertices to find our minimum and maximum.
First, we have (3,7). 4y-3x = 4(7)-3(3)=28-9=19
Next, for (3, -3), we have 4y-3x = 4(-3)-3(3) = -12-9=-21
Finally, for (0.5, 2), we have 4y-3x=4(2)-3(0.5)=8-1.5 = 6.5
Our maximum is 19 when x=3 and y=7 and our minimum is -21 when x=3 and y = -3
The answer would be 1,020 minutes every 30 days
