Answer:
Total tickets = 70
Total cost = $550
Adult's ticket = $9
Child's ticket = $5
Difference = 9 - 5 = $4
Assume all 70 are child's tickets
5 x 70 = 350
But the total cost was 550
550 - 350 = $200
The $200 must have come from Adult's tickets, which has a difference of $4.
200 ÷ 4 = 50
So there are 50 adult's tickets.
70 - 50 = 20
And there are 20 child's tickets.

Answer:
f-1(3)=-2x+6
Step-by-step explanation:
The first step to solving this is to factor out the first perfect square

now factor out the second perfect square

then factor out the second perfect square

the root of a product is equal to the product of the roots of each factor

reduce the index of the radical and exponent with 2 of the first square root
12

reduce the index of the radical and exponent with 2 of the second square root
12x³

reduce the index of the radical and exponent with 2 of the third square root
12x³y²

this means that the correct answer to your question is 12x³y²
