Answer:
x represents the number of level 1 tickets; y represents the number of level 2 tickets
Step-by-step explanation:
The first equation (x + y = 1,000
) shows that x + y equal to the number of seats in the auditorium. That means that they represent the number of tickets. In the second equation (75x + 100y = 25,000) x and y are being multiplied by the cost of their level ticket. So x represents the number of level 1 tickets; y represents the number of level 2 tickets.
hope this helps!
Step-by-step explanation:
y=-2x+1 so we say (-2x+1)
we flip the equation by saying
-2x+1 -1=y+-1
-2x=y-1
Divide both sides by -2
-2÷-1 = y-1÷-2
so x=-1÷2 y=+1÷2
Answer:
Step-by-step explanation:
Be careful how you handle this.
f(-7) = 3(-7)^2
f(-7) = 3* 49 Notice the minus sign disappears. That's because there are 2 of them.
f(-7) = 147
13. 1,6
18. -15,12
19. -7, 1/2
