For
y = (x^2 -4)/((x +2)(x^2 -49))
the numerator factors to (x -2)(x +2), so the factor of (x +2) will cancel with that in the denominator, leaving
y = (x -2)/(x^2 -49)
There are points of discontinuity at the hole, x=-2, and at each of the vertical asymptotes, at x=-7, +7.
The horizontal asymptote is y=0.
Solving the system of equations shows that to make these equations true x=1 and y=0.5

Answer:
Number of senior citizen tickets sold= 110
Number of adults tickets sold= 290
Step-by-step explanation:
<u>First, we need to establish a system of equations:</u>
x= number of adults tickets
y= number of senior citizen tickets
x + y= 400
6x + 3y= 2,070
<u>Now, we isolate x in one equation and substitute the value in the other:</u>
x= 400 - y
6*(400 - y) + 3y = 2,070
2,400 - 6y + 3y = 2,070
330 = 3y
110 = y
Number of senior citizen tickets sold= 110
Number of adults tickets sold= 290
<u>Prove:</u>
290 + 110= 400
6*290 + 3*110= 2,070
