Answer:
21 child tickets.
Step-by-step explanation:
Let x represent number of adult tickets and y represent number of child tickets.
We have been given that on Thursday, three times as many adult tickets as child tickets were sold. We can represent this information in an equation as:
We have been given that at a the movie theater, child admission is $6.10 and adult admission is $9.20.The all tickets were sold for a total of $707.70. We can represent this information in an equation as:
Upon substituting equation (1) in equation (2), we will get:
Therefore, 21 child tickets were sold on Thursday.
Cross multiplication 13x -13 = 8x+12
combining like terms 13x -8x =12 +13
5x= 25 x= 5
x=5

Answer:
(3, 6 ) and (- 3, 18 )
Step-by-step explanation:
Equate the right side of both equations, that is
x² - 2x + 3 = - 2x + 12 ← subtract - 2x + 12 from both sides
x² - 9 = 0 ← in standard form
(x - 3)(x + 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x + 3 = 0 ⇒ x = - 3
Substitute these values into f(x) = - 2x + 12
f(3) = - 2(3) + 12 = - 6 + 12 = 6 ⇒ (3, 6 )
f(- 3) = - 2(- 3) + 12 = 6 + 12 = 18 ⇒ (- 3, 18 )
