To add or subtract fractions, you must find the common denominator. To do this, you must find a factor that is common between the two denominators, in this case its 3 because 4x3=12. So multiple 1/4 by 3 and you should get 3/12. Then simply add and subtract the numerators, so +- is essentially just subtraction so to simplify the equation, it would be 3/12-3/12-5/12. So 3/12-3/12= 0, 0-5/12= -5/12. So the answer is -5/12.
Hope this helps!

Answer:
y=62.0
Step-by-step explanation:
Cosine rule Formula : √a²+b²-2abcos(angle)
=61.98387
Triangle area formula= bh/2
Blue triangle:
10*12/2= 60
Orange triangle:
8*10/2= 40
Add the values: 40+60= 100 in^2
Final answer: 100 in^2
All you have to do is plot the points. Your dependent variable is the ticket sales, so it has to be in the y-axis. The independent variable, days, would be the x-axis. All in all, you would be able to plot 4 points corresponding to the 4 pairs of data given. Then, just connect them to obtain a graph. I used MS Excel to make the graph shown in the figure :)
