Answer:
C: 
Step-by-step explanation:
Amplitude is changed by multiplying the entire trig function by a number, by default the amplitude is 1, so multiplying by 6 is necessary; eliminate A and B
Horizontal shift is going through the x axis, so it must be subtracted from the x value. This is only seen in choice C of the remaining answers.
Calculating the period isn't necessary because we already found the right answer but in case you need it in the future; the period is by default 2pi, to get to pi/4, it had to be 8 times smaller, so multiplying x and translations on x by 8 will get you the correct period.
Answer:
94 Child tickets were sold.
Step-by-step explanation:
Let x represent child tickets
Let y represent adult tickets
Cost Equation: 5.70x + 9.75y = 1306.10
Quantity Equation: x + y = 173
Multiply the Quantity Equation by -5.70
5.70x + 9.75y = 1306.10
-5.70x - 5.70y = -986.10
4.05y = 320.00
÷4.05 ÷4.05
y = 79
x + y = 173
x + 79 = 173
x = 94
