Y = mx
We just need to find the slope:
y2 - y1 / x2 -x1 = -4 - 4 / 1 - - 1 = -8/2 = -4/1 = -4
so: y = -4x
Hope that helps! :)
The difference between the first company and the other is that the first charges $1 less per movie than the second , but charges $15 more than the second as well.
To awnser this problem and equal the charges in bth companies we just need to cancel out the $15 the first company charges more than the second.
As we pay more $1 each movie in the first , we would need to view 15 movies to equalize the charges from both companies :
x= 15 if we want to equalize the charges
f(x) = 4.95(15) + 40
f(x) = 74.25 + 40 = 114.25
g(x) = 5.95(15) + 25
g(x) = 89.25 + 25 = 114.25
Awnser: We would need to view 15 pay per view to equalize the bills from both companies
The answer is A and D because if you square both of them, they are less than 16. hope this helps!
Hope it helped have a great day
