Answer:
0.6827
Step-by-step explanation:
-2(2f-4) = -4(-f+2)
Distribute the -2, multiplying it to each term inside the parentheses.
(-2 × 2f = -4f, and -2 × -4 = 8 because the double negatives cancel)
-4f+8 = -4(-f+2)
Now distribute the -4...
(-4 × -f = 4f, and -4 × 2 = -8)
-4f+8 = 4f-8
Add 4f to each side so that our variable is on just one side of the equation.
8 = 8f-8
To get rid of that -8 and isolate our variable, add 8 to each side.
16 = 8f
Divide each side by 8 to get the value of f.
2 = f
The horizontal stretch is the correct answer. A period is the distance on the x-axis that it takes for the tangent or cotangent function to repeat itself. Stretching it out horizontally will lengthen that distance and therefore change the period.
Answer:
22 tickets
Step-by-step explanation:
Let the number of ticket purchased ahead of time be a and the number of tickets purchased at the door be d.
We know that purchasing ahead of time costs $14 while purchasing at the door costs $25. Writing this in equation form yields:
14a + 25d = 788........i
Now we also know that ticket purchased ahead of time was 5 less than tickets purchased at the door. Hence,
a = d - 5...........ii
We can solve both equations simultaneously .Let's substitute ii into I
14( d -5) + 25d = 788
14d - 70 + 25d = 788
39d - 70 = 788
39d = 788 + 70
39d = 858
d = 858/39 = 22
We know a = d - 5
This mean a = 22 - 5 = 17
