Answer:
the answer is triangle GBL
a = adult ticket price
s = student ticket price
---
7a + 2s = 87
---
4a + 6s = 74
4a = 74 - 6s
a = 74/4 - (6/4)s
a = 37/2 - (3/2)s
---
7a + 2s = 87
7(37/2 - (3/2)s) + 2s = 87
7(37/2) - 7(3/2)s + 2s = 87
(259/2) - (21/2)s + 2s = 87
(21/2)s - 2s = (259/2) - 87
(21/2)s - (4/2)s = 259/2 - 174/2
(17/2)s = 85/2
---
s = 85/2(2/17)
s = 85/17
---
Answer:
s = $5
a = $11

As the x-values got to + infinity, the function's values got to + infinity. This is a graph in which the positive end continues to go up indefinitely, meaning the function's values will end up becoming more and more positive as you go along the positive end of the x axis.
Answer:
3a-b/(x-b)=1/(x+1)Doing criss cross multiplication
3a(x+1)-b(x+1)=x-b
3ax+3a-bx-b=x-b
3ax-bx-x=b-3a-b
x(3a-b-1)=-3a
x=3a/(3a-b-1)
