Answer:
f1+F1=2sin
Step-by-step explanation:
The solution can be found where two lines intersect. The lines in the image do not intersect at an exact point, so we will need to estimate.
The x value is either 1 or -1 from your choices. You can see it is closer to -1 on the horizontal (x axis).
The y value is either 0 or -1 from your choices. You can see it is closer to 0 on the vertical (y axis).
The answer to your set of lines is approximately (-1,0).
Answer:
$19.2
Step-by-step explanation:
20% of 8 is 1.6 (let me know if you need me to explain how to find that).
This means that, with a 20% discount, the price of a ticket would be $6.4.
If there are three of you, multiply 6.4 by 3.
That gets you to 19.2
