28i-49+36i^2-63i
This is the right answer from your problem
Given,
Adult Price(x) =8 $
Child Price(y) =6 $
So, 8x+6y=1500$ and also given 210 tickets were sold
So, x+y=210
By solving those two equations we get
No.of adult tickets sold = 120 & no.of child tickets =90
A straight line parallel to another is one that has the same slope. The generic equation of a line can be written as y-yo = m (x-xo). If we look for a parallel line that passes through the point (8.0). We should look for a line with the values m = -0.75, xo = 8, yo = 0. Substituting in the generic equation, we have that the line sought is y = -0.75 (x-8)
D is correct because y on I doesn't equal y on II.
