A. isn't correct because functions are by their definition different.
B is true. Domain of both is x>0 and range is 1/2 as large. because of 1/2 factor in first function
C is true . because of -2 it is shifted to the right by 2 and it is shrunk vertically by 1/2
D isn't true because ranges are not the same.
Parallel means that it has the same gradient but a different Y intercept.
we know it will be:
y=2x+c but we need to know C. what we can do is substitute in the point it needs to go through.
y=2x+c
5=(1×2)+c
5=2+c
3=c
so the equation is:
y=2x+3
If they manage to sell 
tickets, they will earn 
dollars. We want this number to be at least 1000, so the inequality would be
In order to solve this for t, you only need to divide both sides by 15:
So, they need to sell at least 67 tickets to have an income of
dollars
Step-by-step explanation:

Answer:
A. {4,3}
Step-by-step explanation:
x -2y = -2
y = - 3x +15
x - 2(-3x+15) = -2
x +6x - 30 = -2
7x = 28
x = 4
y = - 3x +15 = - 3*4 + 15 = -12 + 15 = 3
{4,3}
