Answer:the price of one child ticket is $8
the price of one adult ticket is $12
Step-by-step explanation:
Let x represent the price of one child ticket.
Let y represent the price of one adult ticket.
First tour is 4 child tickets and 8 adult tickets for 128 dollars. This means that
4x + 8y = 128 - - - - - - - - - - 1
Second tour is 6 adult tickets for 72 dollars. This means that
6y = 72
y = 72/6 = $12
Substituting y = 12 into equation 1, it becomes
4x + 8 × 12= 128
4x + 96 = 128
4x = 128 - 96
4x = 32
x = 32/4 = $8
Okay of means to multiply
154×1/7= 154÷7= 22
So basicly 22 children arrive for early pick up

Answer: -13 and 2
Step-by-step explanation:
-13 x 2 = -26
-13 + 2 = -11
The answer is g'(x) = 4x² - 72x + 307.
If shifted 9 units right, substitute (x - 9) in place of x.
If shifted 1 unit down afterwards, subtract 1.
- g'(x) = 4(x - 9)² - 16 - 1
- g'(x) = 4(x - 9)² - 17
- g'(x) = 4x² - 72x + 324 - 17
- g'(x) = 4x² - 72x + 307
