Answer:

Option B. 220

Step-by-step explanation:

Let

x ----> the number of student tickets sold

y ----> the number of adult tickets sold

we know that

x+y=360

y=360-x ----> equation A

3x+5y=1,360 ----> equation B

Solve the system by substitution

substitute equation A in equation B

3x+5(360-x)=1,360

solve for x

3x+1,800-5x=1,360

5x-3x=1,800-1,360

2x=440

x=220\ student\ tickets

How would you graph f(x) = 7x + 5 when you reflect it over y axis and translate it 3 units left
SOVA2 [1]

Answer:

See explanation

Step-by-step explanation:

Given the function f(x)=7x+5

1. To reflect the graph of the function f(x) over the y-axis, you should change the slope of the line in opposite. The slope of the function f(x) is 7, so the slope of the reflected function will be -7 and the expression of the reflected function will be

g(x)=-7x+5

2. To translate the function g(x) 3 units left, add 3 units to x, thus the expression for the function will be

h(x)=-7(x+3)+5\\ \\h(x)=-7x-21+5\\ \\h(x)=-7x-16

See attached diagram for details.
