So p - $15 = $49 and to solve it subtract 15 from 49 and then you will get your answer
Y = (-2x +2)^2 +8
(-2x^2 +4) +8
-2x^2 +12
We need to create two expressions, then equate them in order to find the numbers of hours.
Let X = Number of hours
Let 1200+18x = Company A (Flat Fee + Hourly Rate*Hours)
Let 900+23x = Company B

After 60 hours, the prices will be the same
You use the tan/cos/sin rules
So we know that the hypotenuse=46.8, opposite=44
We can use sin (negative) to find it
sin^-1=opp/hyp
sin^-1=44/66.8
=70 degrees
Hope this helps!! :)
